Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978680, here are decompositions:
- 19 + 4294978661 = 4294978680
- 53 + 4294978627 = 4294978680
- 89 + 4294978591 = 4294978680
- 127 + 4294978553 = 4294978680
- 163 + 4294978517 = 4294978680
- 191 + 4294978489 = 4294978680
- 281 + 4294978399 = 4294978680
- 347 + 4294978333 = 4294978680
Showing the first eight; more decompositions exist.
