Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2884, here are decompositions:
- 5 + 2879 = 2884
- 23 + 2861 = 2884
- 41 + 2843 = 2884
- 47 + 2837 = 2884
- 83 + 2801 = 2884
- 107 + 2777 = 2884
- 131 + 2753 = 2884
- 173 + 2711 = 2884
Showing the first eight; more decompositions exist.

The digit sequence 2884 first appears in π at position 33 of the decimal expansion (the 33ordinal-suffix:rd 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.
