Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972940, here are decompositions:
- 43 + 4294972897 = 4294972940
- 73 + 4294972867 = 4294972940
- 79 + 4294972861 = 4294972940
- 151 + 4294972789 = 4294972940
- 277 + 4294972663 = 4294972940
- 283 + 4294972657 = 4294972940
- 331 + 4294972609 = 4294972940
- 337 + 4294972603 = 4294972940
Showing the first eight; more decompositions exist.
