Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975978, here are decompositions:
- 71 + 4294975907 = 4294975978
- 89 + 4294975889 = 4294975978
- 101 + 4294975877 = 4294975978
- 131 + 4294975847 = 4294975978
- 197 + 4294975781 = 4294975978
- 239 + 4294975739 = 4294975978
- 281 + 4294975697 = 4294975978
- 389 + 4294975589 = 4294975978
Showing the first eight; more decompositions exist.
