Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615174, here are decompositions:

5 + 31615169 = 31615174
11 + 31615163 = 31615174
47 + 31615127 = 31615174
113 + 31615061 = 31615174
167 + 31615007 = 31615174
233 + 31614941 = 31615174
293 + 31614881 = 31615174
467 + 31614707 = 31615174

Showing the first eight; more decompositions exist.
