Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31146, here are decompositions:
- 7 + 31139 = 31146
- 23 + 31123 = 31146
- 67 + 31079 = 31146
- 83 + 31063 = 31146
- 107 + 31039 = 31146
- 113 + 31033 = 31146
- 127 + 31019 = 31146
- 163 + 30983 = 31146
Showing the first eight; more decompositions exist.
