Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31152, here are decompositions:
- 5 + 31147 = 31152
- 13 + 31139 = 31152
- 29 + 31123 = 31152
- 31 + 31121 = 31152
- 61 + 31091 = 31152
- 71 + 31081 = 31152
- 73 + 31079 = 31152
- 83 + 31069 = 31152
Showing the first eight; more decompositions exist.
