Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480056, here are decompositions:

7 + 31480049 = 31480056
37 + 31480019 = 31480056
107 + 31479949 = 31480056
109 + 31479947 = 31480056
199 + 31479857 = 31480056
227 + 31479829 = 31480056
239 + 31479817 = 31480056
263 + 31479793 = 31480056

Showing the first eight; more decompositions exist.
