Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117240, here are decompositions:
- 17 + 117223 = 117240
- 31 + 117209 = 117240
- 37 + 117203 = 117240
- 47 + 117193 = 117240
- 73 + 117167 = 117240
- 107 + 117133 = 117240
- 113 + 117127 = 117240
- 131 + 117109 = 117240
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 117,240 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 117240 first appears in π at position 210,309 of the decimal expansion (the 210,309ordinal-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.
