Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453694, here are decompositions:

43 + 31453651 = 31453694
193 + 31453501 = 31453694
211 + 31453483 = 31453694
373 + 31453321 = 31453694
487 + 31453207 = 31453694
523 + 31453171 = 31453694
673 + 31453021 = 31453694
751 + 31452943 = 31453694

Showing the first eight; more decompositions exist.
