Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978208, here are decompositions:

  • 5 + 978203 = 978208
  • 29 + 978179 = 978208
  • 59 + 978149 = 978208
  • 131 + 978077 = 978208
  • 137 + 978071 = 978208
  • 167 + 978041 = 978208
  • 191 + 978017 = 978208
  • 197 + 978011 = 978208

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 978,208 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 978208 first appears in π at position 273,247 of the decimal expansion (the 273,247ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
