Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534246, here are decompositions:

5 + 31534241 = 31534246
47 + 31534199 = 31534246
59 + 31534187 = 31534246
167 + 31534079 = 31534246
173 + 31534073 = 31534246
179 + 31534067 = 31534246
587 + 31533659 = 31534246
647 + 31533599 = 31534246

Showing the first eight; more decompositions exist.
