Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1854, here are decompositions:
- 7 + 1847 = 1854
- 23 + 1831 = 1854
- 31 + 1823 = 1854
- 43 + 1811 = 1854
- 53 + 1801 = 1854
- 67 + 1787 = 1854
- 71 + 1783 = 1854
- 101 + 1753 = 1854
Showing the first eight; more decompositions exist.

The digit sequence 1854 first appears in π at position 446 of the decimal expansion (the 446ordinal-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.
