Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967870, here are decompositions:
- 3 + 4294967867 = 4294967870
- 13 + 4294967857 = 4294967870
- 73 + 4294967797 = 4294967870
- 79 + 4294967791 = 4294967870
- 307 + 4294967563 = 4294967870
- 331 + 4294967539 = 4294967870
- 373 + 4294967497 = 4294967870
- 499 + 4294967371 = 4294967870
Showing the first eight; more decompositions exist.
