Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627894, here are decompositions:

5 + 31627889 = 31627894
83 + 31627811 = 31627894
101 + 31627793 = 31627894
131 + 31627763 = 31627894
167 + 31627727 = 31627894
173 + 31627721 = 31627894
293 + 31627601 = 31627894
317 + 31627577 = 31627894

Showing the first eight; more decompositions exist.
