Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162712, here are decompositions:
- 3 + 162709 = 162712
- 29 + 162683 = 162712
- 41 + 162671 = 162712
- 71 + 162641 = 162712
- 83 + 162629 = 162712
- 89 + 162623 = 162712
- 101 + 162611 = 162712
- 149 + 162563 = 162712
Showing the first eight; more decompositions exist.
