Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975178, here are decompositions:
- 31 + 4294975147 = 4294975178
- 61 + 4294975117 = 4294975178
- 127 + 4294975051 = 4294975178
- 181 + 4294974997 = 4294975178
- 367 + 4294974811 = 4294975178
- 409 + 4294974769 = 4294975178
- 661 + 4294974517 = 4294975178
- 727 + 4294974451 = 4294975178
Showing the first eight; more decompositions exist.
