Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447076, here are decompositions:

7 + 31447069 = 31447076
79 + 31446997 = 31447076
103 + 31446973 = 31447076
127 + 31446949 = 31447076
139 + 31446937 = 31447076
223 + 31446853 = 31447076
229 + 31446847 = 31447076
307 + 31446769 = 31447076

Showing the first eight; more decompositions exist.
