Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127756, here are decompositions:
- 17 + 127739 = 127756
- 23 + 127733 = 127756
- 29 + 127727 = 127756
- 47 + 127709 = 127756
- 53 + 127703 = 127756
- 107 + 127649 = 127756
- 113 + 127643 = 127756
- 149 + 127607 = 127756
Showing the first eight; more decompositions exist.
