Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975870, here are decompositions:
- 23 + 4294975847 = 4294975870
- 89 + 4294975781 = 4294975870
- 113 + 4294975757 = 4294975870
- 131 + 4294975739 = 4294975870
- 137 + 4294975733 = 4294975870
- 173 + 4294975697 = 4294975870
- 197 + 4294975673 = 4294975870
- 281 + 4294975589 = 4294975870
Showing the first eight; more decompositions exist.
