Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627854, here are decompositions:

43 + 31627811 = 31627854
53 + 31627801 = 31627854
61 + 31627793 = 31627854
101 + 31627753 = 31627854
103 + 31627751 = 31627854
127 + 31627727 = 31627854
227 + 31627627 = 31627854
277 + 31627577 = 31627854

Showing the first eight; more decompositions exist.
