Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447082, here are decompositions:

3 + 31447079 = 31447082
13 + 31447069 = 31447082
61 + 31447021 = 31447082
109 + 31446973 = 31447082
211 + 31446871 = 31447082
223 + 31446859 = 31447082
229 + 31446853 = 31447082
313 + 31446769 = 31447082

Showing the first eight; more decompositions exist.
