Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975990, here are decompositions:
- 3 + 4294975987 = 4294975990
- 83 + 4294975907 = 4294975990
- 101 + 4294975889 = 4294975990
- 113 + 4294975877 = 4294975990
- 197 + 4294975793 = 4294975990
- 233 + 4294975757 = 4294975990
- 251 + 4294975739 = 4294975990
- 257 + 4294975733 = 4294975990
Showing the first eight; more decompositions exist.
