Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971628, here are decompositions:
- 71 + 4294971557 = 4294971628
- 131 + 4294971497 = 4294971628
- 137 + 4294971491 = 4294971628
- 197 + 4294971431 = 4294971628
- 239 + 4294971389 = 4294971628
- 251 + 4294971377 = 4294971628
- 359 + 4294971269 = 4294971628
- 401 + 4294971227 = 4294971628
Showing the first eight; more decompositions exist.
