Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157992, here are decompositions:
- 41 + 157951 = 157992
- 59 + 157933 = 157992
- 61 + 157931 = 157992
- 103 + 157889 = 157992
- 151 + 157841 = 157992
- 179 + 157813 = 157992
- 193 + 157799 = 157992
- 199 + 157793 = 157992
Showing the first eight; more decompositions exist.
