Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115478, here are decompositions:

  • 7 + 115471 = 115478
  • 19 + 115459 = 115478
  • 79 + 115399 = 115478
  • 151 + 115327 = 115478
  • 157 + 115321 = 115478
  • 199 + 115279 = 115478
  • 229 + 115249 = 115478
  • 241 + 115237 = 115478

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 115,478 and was likely granted around 1871.

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

Position in π

The digit sequence 115478 first appears in π at position 436,354 of the decimal expansion (the 436,354ordinal-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.
