Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1908, here are decompositions:
- 7 + 1901 = 1908
- 19 + 1889 = 1908
- 29 + 1879 = 1908
- 31 + 1877 = 1908
- 37 + 1871 = 1908
- 41 + 1867 = 1908
- 47 + 1861 = 1908
- 61 + 1847 = 1908
Showing the first eight; more decompositions exist.

The digit sequence 1908 first appears in π at position 9,510 of the decimal expansion (the 9,510ordinal-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.
