Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49686, here are decompositions:
- 5 + 49681 = 49686
- 17 + 49669 = 49686
- 19 + 49667 = 49686
- 23 + 49663 = 49686
- 47 + 49639 = 49686
- 53 + 49633 = 49686
- 59 + 49627 = 49686
- 73 + 49613 = 49686
Showing the first eight; more decompositions exist.
