Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972894, here are decompositions:
- 71 + 4294972823 = 4294972894
- 101 + 4294972793 = 4294972894
- 167 + 4294972727 = 4294972894
- 281 + 4294972613 = 4294972894
- 461 + 4294972433 = 4294972894
- 557 + 4294972337 = 4294972894
- 587 + 4294972307 = 4294972894
- 743 + 4294972151 = 4294972894
Showing the first eight; more decompositions exist.
