Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31056, here are decompositions:

5 + 31051 = 31056
17 + 31039 = 31056
23 + 31033 = 31056
37 + 31019 = 31056
43 + 31013 = 31056
73 + 30983 = 31056
79 + 30977 = 31056
107 + 30949 = 31056

Showing the first eight; more decompositions exist.
