Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137712, here are decompositions:
- 5 + 137707 = 137712
- 13 + 137699 = 137712
- 53 + 137659 = 137712
- 59 + 137653 = 137712
- 73 + 137639 = 137712
- 79 + 137633 = 137712
- 89 + 137623 = 137712
- 139 + 137573 = 137712
Showing the first eight; more decompositions exist.
