Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967778, here are decompositions:
- 19 + 4294967759 = 4294967778
- 97 + 4294967681 = 4294967778
- 139 + 4294967639 = 4294967778
- 151 + 4294967627 = 4294967778
- 181 + 4294967597 = 4294967778
- 229 + 4294967549 = 4294967778
- 239 + 4294967539 = 4294967778
- 281 + 4294967497 = 4294967778
Showing the first eight; more decompositions exist.
