Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157506, here are decompositions:
- 17 + 157489 = 157506
- 23 + 157483 = 157506
- 29 + 157477 = 157506
- 73 + 157433 = 157506
- 79 + 157427 = 157506
- 113 + 157393 = 157506
- 157 + 157349 = 157506
- 179 + 157327 = 157506
Showing the first eight; more decompositions exist.
