Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460754, here are decompositions:

11 + 31460743 = 31460754
37 + 31460717 = 31460754
53 + 31460701 = 31460754
97 + 31460657 = 31460754
107 + 31460647 = 31460754
173 + 31460581 = 31460754
257 + 31460497 = 31460754
263 + 31460491 = 31460754

Showing the first eight; more decompositions exist.
