Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975438, here are decompositions:
- 41 + 4294975397 = 4294975438
- 227 + 4294975211 = 4294975438
- 359 + 4294975079 = 4294975438
- 401 + 4294975037 = 4294975438
- 521 + 4294974917 = 4294975438
- 557 + 4294974881 = 4294975438
- 701 + 4294974737 = 4294975438
- 797 + 4294974641 = 4294975438
Showing the first eight; more decompositions exist.
