Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972972, here are decompositions:
- 41 + 4294972931 = 4294972972
- 113 + 4294972859 = 4294972972
- 149 + 4294972823 = 4294972972
- 179 + 4294972793 = 4294972972
- 359 + 4294972613 = 4294972972
- 491 + 4294972481 = 4294972972
- 821 + 4294972151 = 4294972972
- 863 + 4294972109 = 4294972972
Showing the first eight; more decompositions exist.
