Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167664, here are decompositions:
- 23 + 167641 = 167664
- 31 + 167633 = 167664
- 37 + 167627 = 167664
- 41 + 167623 = 167664
- 43 + 167621 = 167664
- 53 + 167611 = 167664
- 67 + 167597 = 167664
- 71 + 167593 = 167664
Showing the first eight; more decompositions exist.
