Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974128, here are decompositions:
- 79 + 4294974049 = 4294974128
- 139 + 4294973989 = 4294974128
- 229 + 4294973899 = 4294974128
- 337 + 4294973791 = 4294974128
- 457 + 4294973671 = 4294974128
- 499 + 4294973629 = 4294974128
- 541 + 4294973587 = 4294974128
- 631 + 4294973497 = 4294974128
Showing the first eight; more decompositions exist.
