Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157406, here are decompositions:
- 13 + 157393 = 157406
- 43 + 157363 = 157406
- 79 + 157327 = 157406
- 103 + 157303 = 157406
- 127 + 157279 = 157406
- 163 + 157243 = 157406
- 199 + 157207 = 157406
- 229 + 157177 = 157406
Showing the first eight; more decompositions exist.
