Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972938, here are decompositions:
- 7 + 4294972931 = 4294972938
- 41 + 4294972897 = 4294972938
- 71 + 4294972867 = 4294972938
- 79 + 4294972859 = 4294972938
- 131 + 4294972807 = 4294972938
- 149 + 4294972789 = 4294972938
- 211 + 4294972727 = 4294972938
- 281 + 4294972657 = 4294972938
Showing the first eight; more decompositions exist.
