Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157566, here are decompositions:
- 5 + 157561 = 157566
- 7 + 157559 = 157566
- 23 + 157543 = 157566
- 43 + 157523 = 157566
- 47 + 157519 = 157566
- 53 + 157513 = 157566
- 83 + 157483 = 157566
- 89 + 157477 = 157566
Showing the first eight; more decompositions exist.
