Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978072, here are decompositions:

  • 5 + 978067 = 978072
  • 19 + 978053 = 978072
  • 23 + 978049 = 978072
  • 31 + 978041 = 978072
  • 41 + 978031 = 978072
  • 61 + 978011 = 978072
  • 71 + 978001 = 978072
  • 101 + 977971 = 978072

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 978,072 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 978072 first appears in π at position 744,575 of the decimal expansion (the 744,575ordinal-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.
