Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111240, here are decompositions:
- 11 + 111229 = 111240
- 13 + 111227 = 111240
- 23 + 111217 = 111240
- 29 + 111211 = 111240
- 53 + 111187 = 111240
- 97 + 111143 = 111240
- 113 + 111127 = 111240
- 131 + 111109 = 111240
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 111,240 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 111240 first appears in π at position 48,666 of the decimal expansion (the 48,666ordinal-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.
