Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626082, here are decompositions:

3 + 31626079 = 31626082
29 + 31626053 = 31626082
41 + 31626041 = 31626082
71 + 31626011 = 31626082
101 + 31625981 = 31626082
113 + 31625969 = 31626082
233 + 31625849 = 31626082
239 + 31625843 = 31626082

Showing the first eight; more decompositions exist.
