Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627078, here are decompositions:

5 + 31627073 = 31627078
71 + 31627007 = 31627078
101 + 31626977 = 31627078
179 + 31626899 = 31627078
239 + 31626839 = 31627078
251 + 31626827 = 31627078
281 + 31626797 = 31627078
311 + 31626767 = 31627078

Showing the first eight; more decompositions exist.
