Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157108, here are decompositions:
- 5 + 157103 = 157108
- 47 + 157061 = 157108
- 59 + 157049 = 157108
- 71 + 157037 = 157108
- 89 + 157019 = 157108
- 101 + 157007 = 157108
- 137 + 156971 = 157108
- 167 + 156941 = 157108
Showing the first eight; more decompositions exist.
