Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157526, here are decompositions:
- 3 + 157523 = 157526
- 7 + 157519 = 157526
- 13 + 157513 = 157526
- 37 + 157489 = 157526
- 43 + 157483 = 157526
- 97 + 157429 = 157526
- 163 + 157363 = 157526
- 199 + 157327 = 157526
Showing the first eight; more decompositions exist.
