Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972978, here are decompositions:
- 47 + 4294972931 = 4294972978
- 227 + 4294972751 = 4294972978
- 251 + 4294972727 = 4294972978
- 419 + 4294972559 = 4294972978
- 557 + 4294972421 = 4294972978
- 641 + 4294972337 = 4294972978
- 827 + 4294972151 = 4294972978
- 929 + 4294972049 = 4294972978
Showing the first eight; more decompositions exist.
