Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971818, here are decompositions:
- 37 + 4294971781 = 4294971818
- 211 + 4294971607 = 4294971818
- 349 + 4294971469 = 4294971818
- 439 + 4294971379 = 4294971818
- 619 + 4294971199 = 4294971818
- 691 + 4294971127 = 4294971818
- 1069 + 4294970749 = 4294971818
- 1249 + 4294970569 = 4294971818
Showing the first eight; more decompositions exist.
