Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974728, here are decompositions:
- 211 + 4294974517 = 4294974728
- 271 + 4294974457 = 4294974728
- 277 + 4294974451 = 4294974728
- 367 + 4294974361 = 4294974728
- 397 + 4294974331 = 4294974728
- 739 + 4294973989 = 4294974728
- 829 + 4294973899 = 4294974728
- 859 + 4294973869 = 4294974728
Showing the first eight; more decompositions exist.
