Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465056, here are decompositions:

17 + 31465039 = 31465056
23 + 31465033 = 31465056
53 + 31465003 = 31465056
83 + 31464973 = 31465056
89 + 31464967 = 31465056
109 + 31464947 = 31465056
173 + 31464883 = 31465056
229 + 31464827 = 31465056

Showing the first eight; more decompositions exist.
