Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975816, here are decompositions:
- 23 + 4294975793 = 4294975816
- 59 + 4294975757 = 4294975816
- 83 + 4294975733 = 4294975816
- 167 + 4294975649 = 4294975816
- 227 + 4294975589 = 4294975816
- 269 + 4294975547 = 4294975816
- 317 + 4294975499 = 4294975816
- 353 + 4294975463 = 4294975816
Showing the first eight; more decompositions exist.
