Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1874, here are decompositions:
- 3 + 1871 = 1874
- 7 + 1867 = 1874
- 13 + 1861 = 1874
- 43 + 1831 = 1874
- 73 + 1801 = 1874
- 97 + 1777 = 1874
- 127 + 1747 = 1874
- 151 + 1723 = 1874
Showing the first eight; more decompositions exist.

The digit sequence 1874 first appears in π at position 6,380 of the decimal expansion (the 6,380ordinal-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.
