Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574082, here are decompositions:

11 + 31574071 = 31574082
41 + 31574041 = 31574082
61 + 31574021 = 31574082
83 + 31573999 = 31574082
151 + 31573931 = 31574082
223 + 31573859 = 31574082
229 + 31573853 = 31574082
251 + 31573831 = 31574082

Showing the first eight; more decompositions exist.
