Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972816, here are decompositions:
- 23 + 4294972793 = 4294972816
- 89 + 4294972727 = 4294972816
- 257 + 4294972559 = 4294972816
- 383 + 4294972433 = 4294972816
- 479 + 4294972337 = 4294972816
- 509 + 4294972307 = 4294972816
- 887 + 4294971929 = 4294972816
- 1259 + 4294971557 = 4294972816
Showing the first eight; more decompositions exist.
