Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534046, here are decompositions:

13 + 31534033 = 31534046
67 + 31533979 = 31534046
79 + 31533967 = 31534046
97 + 31533949 = 31534046
127 + 31533919 = 31534046
199 + 31533847 = 31534046
223 + 31533823 = 31534046
277 + 31533769 = 31534046

Showing the first eight; more decompositions exist.
