Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142606, here are decompositions:
- 5 + 142601 = 142606
- 17 + 142589 = 142606
- 47 + 142559 = 142606
- 53 + 142553 = 142606
- 59 + 142547 = 142606
- 137 + 142469 = 142606
- 173 + 142433 = 142606
- 179 + 142427 = 142606
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 142,606 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 142606 first appears in π at position 187,065 of the decimal expansion (the 187,065ordinal-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.
