Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628326, here are decompositions:

53 + 31628273 = 31628326
227 + 31628099 = 31628326
347 + 31627979 = 31628326
563 + 31627763 = 31628326
599 + 31627727 = 31628326
677 + 31627649 = 31628326
953 + 31627373 = 31628326
1109 + 31627217 = 31628326

Showing the first eight; more decompositions exist.
