Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972918, here are decompositions:
- 59 + 4294972859 = 4294972918
- 167 + 4294972751 = 4294972918
- 191 + 4294972727 = 4294972918
- 359 + 4294972559 = 4294972918
- 809 + 4294972109 = 4294972918
- 839 + 4294972079 = 4294972918
- 857 + 4294972061 = 4294972918
- 881 + 4294972037 = 4294972918
Showing the first eight; more decompositions exist.
