Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1884, here are decompositions:
- 5 + 1879 = 1884
- 7 + 1877 = 1884
- 11 + 1873 = 1884
- 13 + 1871 = 1884
- 17 + 1867 = 1884
- 23 + 1861 = 1884
- 37 + 1847 = 1884
- 53 + 1831 = 1884
Showing the first eight; more decompositions exist.

The digit sequence 1884 first appears in π at position 15,937 of the decimal expansion (the 15,937ordinal-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.
