Goldbach decomposition

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.
