Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615552, here are decompositions:

113 + 31615439 = 31615552
149 + 31615403 = 31615552
239 + 31615313 = 31615552
359 + 31615193 = 31615552
383 + 31615169 = 31615552
389 + 31615163 = 31615552
443 + 31615109 = 31615552
491 + 31615061 = 31615552

Showing the first eight; more decompositions exist.
