Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975678, here are decompositions:
- 5 + 4294975673 = 4294975678
- 29 + 4294975649 = 4294975678
- 89 + 4294975589 = 4294975678
- 131 + 4294975547 = 4294975678
- 179 + 4294975499 = 4294975678
- 281 + 4294975397 = 4294975678
- 449 + 4294975229 = 4294975678
- 467 + 4294975211 = 4294975678
Showing the first eight; more decompositions exist.
