Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453652, here are decompositions:

151 + 31453501 = 31453652
331 + 31453321 = 31453652
613 + 31453039 = 31453652
631 + 31453021 = 31453652
709 + 31452943 = 31453652
751 + 31452901 = 31453652
823 + 31452829 = 31453652
859 + 31452793 = 31453652

Showing the first eight; more decompositions exist.
