Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453484, here are decompositions:

37 + 31453447 = 31453484
151 + 31453333 = 31453484
163 + 31453321 = 31453484
277 + 31453207 = 31453484
313 + 31453171 = 31453484
463 + 31453021 = 31453484
541 + 31452943 = 31453484
691 + 31452793 = 31453484

Showing the first eight; more decompositions exist.
