Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453964, here are decompositions:

7 + 31453957 = 31453964
67 + 31453897 = 31453964
97 + 31453867 = 31453964
151 + 31453813 = 31453964
181 + 31453783 = 31453964
313 + 31453651 = 31453964
457 + 31453507 = 31453964
463 + 31453501 = 31453964

Showing the first eight; more decompositions exist.
