Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627848, here are decompositions:

37 + 31627811 = 31627848
47 + 31627801 = 31627848
97 + 31627751 = 31627848
127 + 31627721 = 31627848
199 + 31627649 = 31627848
271 + 31627577 = 31627848
281 + 31627567 = 31627848
311 + 31627537 = 31627848

Showing the first eight; more decompositions exist.
