Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124146, here are decompositions:
- 7 + 124139 = 124146
- 13 + 124133 = 124146
- 23 + 124123 = 124146
- 59 + 124087 = 124146
- 79 + 124067 = 124146
- 149 + 123997 = 124146
- 157 + 123989 = 124146
- 163 + 123983 = 124146
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 124,146 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 124146 first appears in π at position 129,516 of the decimal expansion (the 129,516ordinal-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.
