Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157536, here are decompositions:
- 13 + 157523 = 157536
- 17 + 157519 = 157536
- 23 + 157513 = 157536
- 47 + 157489 = 157536
- 53 + 157483 = 157536
- 59 + 157477 = 157536
- 79 + 157457 = 157536
- 103 + 157433 = 157536
Showing the first eight; more decompositions exist.
