Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975888, here are decompositions:
- 11 + 4294975877 = 4294975888
- 41 + 4294975847 = 4294975888
- 107 + 4294975781 = 4294975888
- 131 + 4294975757 = 4294975888
- 149 + 4294975739 = 4294975888
- 191 + 4294975697 = 4294975888
- 239 + 4294975649 = 4294975888
- 389 + 4294975499 = 4294975888
Showing the first eight; more decompositions exist.
