Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111248, here are decompositions:
- 19 + 111229 = 111248
- 31 + 111217 = 111248
- 37 + 111211 = 111248
- 61 + 111187 = 111248
- 127 + 111121 = 111248
- 139 + 111109 = 111248
- 157 + 111091 = 111248
- 199 + 111049 = 111248
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 111,248 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 111248 first appears in π at position 471,775 of the decimal expansion (the 471,775ordinal-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.
