Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971866, here are decompositions:
- 7 + 4294971859 = 4294971866
- 37 + 4294971829 = 4294971866
- 193 + 4294971673 = 4294971866
- 223 + 4294971643 = 4294971866
- 397 + 4294971469 = 4294971866
- 487 + 4294971379 = 4294971866
- 499 + 4294971367 = 4294971866
- 739 + 4294971127 = 4294971866
Showing the first eight; more decompositions exist.
