Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958728, here are decompositions:
- 17 + 4294958711 = 4294958728
- 101 + 4294958627 = 4294958728
- 107 + 4294958621 = 4294958728
- 131 + 4294958597 = 4294958728
- 191 + 4294958537 = 4294958728
- 479 + 4294958249 = 4294958728
- 491 + 4294958237 = 4294958728
- 659 + 4294958069 = 4294958728
Showing the first eight; more decompositions exist.
