Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615044, here are decompositions:

5 + 31615039 = 31615044
31 + 31615013 = 31615044
37 + 31615007 = 31615044
101 + 31614943 = 31615044
103 + 31614941 = 31615044
163 + 31614881 = 31615044
191 + 31614853 = 31615044
193 + 31614851 = 31615044

Showing the first eight; more decompositions exist.
