Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2576, here are decompositions:
- 19 + 2557 = 2576
- 37 + 2539 = 2576
- 73 + 2503 = 2576
- 103 + 2473 = 2576
- 109 + 2467 = 2576
- 139 + 2437 = 2576
- 193 + 2383 = 2576
- 199 + 2377 = 2576
Showing the first eight; more decompositions exist.
