Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49742, here are decompositions:
- 3 + 49739 = 49742
- 31 + 49711 = 49742
- 61 + 49681 = 49742
- 73 + 49669 = 49742
- 79 + 49663 = 49742
- 103 + 49639 = 49742
- 109 + 49633 = 49742
- 139 + 49603 = 49742
Showing the first eight; more decompositions exist.
