Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49790, here are decompositions:
- 3 + 49787 = 49790
- 7 + 49783 = 49790
- 43 + 49747 = 49790
- 79 + 49711 = 49790
- 109 + 49681 = 49790
- 127 + 49663 = 49790
- 151 + 49639 = 49790
- 157 + 49633 = 49790
Showing the first eight; more decompositions exist.
