Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971988, here are decompositions:
- 59 + 4294971929 = 4294971988
- 431 + 4294971557 = 4294971988
- 491 + 4294971497 = 4294971988
- 557 + 4294971431 = 4294971988
- 599 + 4294971389 = 4294971988
- 719 + 4294971269 = 4294971988
- 761 + 4294971227 = 4294971988
- 887 + 4294971101 = 4294971988
Showing the first eight; more decompositions exist.
