Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627748, here are decompositions:

109 + 31627639 = 31627748
181 + 31627567 = 31627748
211 + 31627537 = 31627748
337 + 31627411 = 31627748
487 + 31627261 = 31627748
499 + 31627249 = 31627748
547 + 31627201 = 31627748
769 + 31626979 = 31627748

Showing the first eight; more decompositions exist.
