Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975278, here are decompositions:
- 67 + 4294975211 = 4294975278
- 131 + 4294975147 = 4294975278
- 199 + 4294975079 = 4294975278
- 227 + 4294975051 = 4294975278
- 241 + 4294975037 = 4294975278
- 281 + 4294974997 = 4294975278
- 359 + 4294974919 = 4294975278
- 397 + 4294974881 = 4294975278
Showing the first eight; more decompositions exist.
