Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31124, here are decompositions:

3 + 31121 = 31124
43 + 31081 = 31124
61 + 31063 = 31124
73 + 31051 = 31124
193 + 30931 = 31124
271 + 30853 = 31124
283 + 30841 = 31124
307 + 30817 = 31124

Showing the first eight; more decompositions exist.
