Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971786, here are decompositions:
- 5 + 4294971781 = 4294971786
- 113 + 4294971673 = 4294971786
- 179 + 4294971607 = 4294971786
- 223 + 4294971563 = 4294971786
- 229 + 4294971557 = 4294971786
- 283 + 4294971503 = 4294971786
- 317 + 4294971469 = 4294971786
- 397 + 4294971389 = 4294971786
Showing the first eight; more decompositions exist.
