Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1846, here are decompositions:
- 23 + 1823 = 1846
- 59 + 1787 = 1846
- 113 + 1733 = 1846
- 137 + 1709 = 1846
- 149 + 1697 = 1846
- 179 + 1667 = 1846
- 227 + 1619 = 1846
- 233 + 1613 = 1846
Showing the first eight; more decompositions exist.

The digit sequence 1846 first appears in π at position 587 of the decimal expansion (the 587ordinal-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.
