Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157508, here are decompositions:
- 19 + 157489 = 157508
- 31 + 157477 = 157508
- 79 + 157429 = 157508
- 97 + 157411 = 157508
- 157 + 157351 = 157508
- 181 + 157327 = 157508
- 229 + 157279 = 157508
- 277 + 157231 = 157508
Showing the first eight; more decompositions exist.
