Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157612, here are decompositions:
- 41 + 157571 = 157612
- 53 + 157559 = 157612
- 89 + 157523 = 157612
- 179 + 157433 = 157612
- 263 + 157349 = 157612
- 353 + 157259 = 157612
- 359 + 157253 = 157612
- 383 + 157229 = 157612
Showing the first eight; more decompositions exist.
