Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975180, here are decompositions:
- 17 + 4294975163 = 4294975180
- 71 + 4294975109 = 4294975180
- 101 + 4294975079 = 4294975180
- 137 + 4294975043 = 4294975180
- 149 + 4294975031 = 4294975180
- 227 + 4294974953 = 4294975180
- 257 + 4294974923 = 4294975180
- 263 + 4294974917 = 4294975180
Showing the first eight; more decompositions exist.
