Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975138, here are decompositions:
- 29 + 4294975109 = 4294975138
- 59 + 4294975079 = 4294975138
- 101 + 4294975037 = 4294975138
- 107 + 4294975031 = 4294975138
- 257 + 4294974881 = 4294975138
- 401 + 4294974737 = 4294975138
- 491 + 4294974647 = 4294975138
- 557 + 4294974581 = 4294975138
Showing the first eight; more decompositions exist.
