Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135672, here are decompositions:
- 11 + 135661 = 135672
- 23 + 135649 = 135672
- 59 + 135613 = 135672
- 71 + 135601 = 135672
- 73 + 135599 = 135672
- 79 + 135593 = 135672
- 83 + 135589 = 135672
- 101 + 135571 = 135672
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 135,672 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 135672 first appears in π at position 91,045 of the decimal expansion (the 91,045ordinal-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.
