Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453488, here are decompositions:

5 + 31453483 = 31453488
41 + 31453447 = 31453488
61 + 31453427 = 31453488
67 + 31453421 = 31453488
97 + 31453391 = 31453488
127 + 31453361 = 31453488
167 + 31453321 = 31453488
239 + 31453249 = 31453488

Showing the first eight; more decompositions exist.
