Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142906, here are decompositions:
- 3 + 142903 = 142906
- 107 + 142799 = 142906
- 149 + 142757 = 142906
- 173 + 142733 = 142906
- 233 + 142673 = 142906
- 317 + 142589 = 142906
- 347 + 142559 = 142906
- 353 + 142553 = 142906
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 142,906 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 142906 first appears in π at position 342,513 of the decimal expansion (the 342,513ordinal-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.
