Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453426, here are decompositions:

5 + 31453421 = 31453426
233 + 31453193 = 31453426
269 + 31453157 = 31453426
293 + 31453133 = 31453426
449 + 31452977 = 31453426
677 + 31452749 = 31453426
743 + 31452683 = 31453426
827 + 31452599 = 31453426

Showing the first eight; more decompositions exist.
