Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627246, here are decompositions:

3 + 31627243 = 31627246
29 + 31627217 = 31627246
113 + 31627133 = 31627246
173 + 31627073 = 31627246
239 + 31627007 = 31627246
269 + 31626977 = 31627246
347 + 31626899 = 31627246
353 + 31626893 = 31627246

Showing the first eight; more decompositions exist.
