Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453544, here are decompositions:

37 + 31453507 = 31453544
43 + 31453501 = 31453544
61 + 31453483 = 31453544
97 + 31453447 = 31453544
151 + 31453393 = 31453544
211 + 31453333 = 31453544
223 + 31453321 = 31453544
277 + 31453267 = 31453544

Showing the first eight; more decompositions exist.
