Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6126, here are decompositions:
- 5 + 6121 = 6126
- 13 + 6113 = 6126
- 37 + 6089 = 6126
- 47 + 6079 = 6126
- 53 + 6073 = 6126
- 59 + 6067 = 6126
- 73 + 6053 = 6126
- 79 + 6047 = 6126
Showing the first eight; more decompositions exist.
