Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976942, here are decompositions:
- 13 + 4294976929 = 4294976942
- 103 + 4294976839 = 4294976942
- 199 + 4294976743 = 4294976942
- 211 + 4294976731 = 4294976942
- 601 + 4294976341 = 4294976942
- 631 + 4294976311 = 4294976942
- 661 + 4294976281 = 4294976942
- 673 + 4294976269 = 4294976942
Showing the first eight; more decompositions exist.
