Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157584, here are decompositions:
- 5 + 157579 = 157584
- 13 + 157571 = 157584
- 23 + 157561 = 157584
- 41 + 157543 = 157584
- 61 + 157523 = 157584
- 71 + 157513 = 157584
- 101 + 157483 = 157584
- 107 + 157477 = 157584
Showing the first eight; more decompositions exist.
