Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31192, here are decompositions:
- 3 + 31189 = 31192
- 11 + 31181 = 31192
- 41 + 31151 = 31192
- 53 + 31139 = 31192
- 71 + 31121 = 31192
- 101 + 31091 = 31192
- 113 + 31079 = 31192
- 173 + 31019 = 31192
Showing the first eight; more decompositions exist.
