Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457122, here are decompositions:
- 3 + 31457119 = 31457122
- 23 + 31457099 = 31457122
- 29 + 31457093 = 31457122
- 41 + 31457081 = 31457122
- 71 + 31457051 = 31457122
- 83 + 31457039 = 31457122
- 113 + 31457009 = 31457122
- 173 + 31456949 = 31457122
Showing the first eight; more decompositions exist.
