Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972438, here are decompositions:
- 5 + 4294972433 = 4294972438
- 17 + 4294972421 = 4294972438
- 101 + 4294972337 = 4294972438
- 131 + 4294972307 = 4294972438
- 359 + 4294972079 = 4294972438
- 389 + 4294972049 = 4294972438
- 401 + 4294972037 = 4294972438
- 509 + 4294971929 = 4294972438
Showing the first eight; more decompositions exist.
