Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975272, here are decompositions:
- 43 + 4294975229 = 4294975272
- 61 + 4294975211 = 4294975272
- 109 + 4294975163 = 4294975272
- 149 + 4294975123 = 4294975272
- 163 + 4294975109 = 4294975272
- 179 + 4294975093 = 4294975272
- 193 + 4294975079 = 4294975272
- 229 + 4294975043 = 4294975272
Showing the first eight; more decompositions exist.
