Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453514, here are decompositions:

7 + 31453507 = 31453514
13 + 31453501 = 31453514
31 + 31453483 = 31453514
67 + 31453447 = 31453514
181 + 31453333 = 31453514
193 + 31453321 = 31453514
307 + 31453207 = 31453514
373 + 31453141 = 31453514

Showing the first eight; more decompositions exist.
