Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31126, here are decompositions:
- 3 + 31123 = 31126
- 5 + 31121 = 31126
- 47 + 31079 = 31126
- 107 + 31019 = 31126
- 113 + 31013 = 31126
- 149 + 30977 = 31126
- 233 + 30893 = 31126
- 257 + 30869 = 31126
Showing the first eight; more decompositions exist.
