Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1844, here are decompositions:
- 13 + 1831 = 1844
- 43 + 1801 = 1844
- 61 + 1783 = 1844
- 67 + 1777 = 1844
- 97 + 1747 = 1844
- 103 + 1741 = 1844
- 151 + 1693 = 1844
- 181 + 1663 = 1844
Showing the first eight; more decompositions exist.

The digit sequence 1844 first appears in π at position 9,081 of the decimal expansion (the 9,081ordinal-suffix:st 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.
