Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627942, here are decompositions:

11 + 31627931 = 31627942
53 + 31627889 = 31627942
131 + 31627811 = 31627942
149 + 31627793 = 31627942
179 + 31627763 = 31627942
191 + 31627751 = 31627942
293 + 31627649 = 31627942
383 + 31627559 = 31627942

Showing the first eight; more decompositions exist.
