Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453374, here are decompositions:

13 + 31453361 = 31453374
41 + 31453333 = 31453374
53 + 31453321 = 31453374
107 + 31453267 = 31453374
167 + 31453207 = 31453374
181 + 31453193 = 31453374
193 + 31453181 = 31453374
233 + 31453141 = 31453374

Showing the first eight; more decompositions exist.
