Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117642, here are decompositions:
- 23 + 117619 = 117642
- 71 + 117571 = 117642
- 79 + 117563 = 117642
- 101 + 117541 = 117642
- 103 + 117539 = 117642
- 113 + 117529 = 117642
- 131 + 117511 = 117642
- 139 + 117503 = 117642
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 117,642 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 117642 first appears in π at position 136,196 of the decimal expansion (the 136,196ordinal-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.
