Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452748, here are decompositions:

17 + 31452731 = 31452748
29 + 31452719 = 31452748
71 + 31452677 = 31452748
149 + 31452599 = 31452748
227 + 31452521 = 31452748
251 + 31452497 = 31452748
347 + 31452401 = 31452748
617 + 31452131 = 31452748

Showing the first eight; more decompositions exist.
