Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974278, here are decompositions:
- 139 + 4294974139 = 4294974278
- 229 + 4294974049 = 4294974278
- 367 + 4294973911 = 4294974278
- 379 + 4294973899 = 4294974278
- 409 + 4294973869 = 4294974278
- 487 + 4294973791 = 4294974278
- 607 + 4294973671 = 4294974278
- 691 + 4294973587 = 4294974278
Showing the first eight; more decompositions exist.
