Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975128, here are decompositions:
- 5 + 4294975123 = 4294975128
- 11 + 4294975117 = 4294975128
- 19 + 4294975109 = 4294975128
- 71 + 4294975057 = 4294975128
- 97 + 4294975031 = 4294975128
- 131 + 4294974997 = 4294975128
- 137 + 4294974991 = 4294975128
- 211 + 4294974917 = 4294975128
Showing the first eight; more decompositions exist.
