Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453704, here are decompositions:

5 + 31453699 = 31453704
53 + 31453651 = 31453704
127 + 31453577 = 31453704
181 + 31453523 = 31453704
197 + 31453507 = 31453704
241 + 31453463 = 31453704
257 + 31453447 = 31453704
277 + 31453427 = 31453704

Showing the first eight; more decompositions exist.
