Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534072, here are decompositions:

5 + 31534067 = 31534072
113 + 31533959 = 31534072
149 + 31533923 = 31534072
233 + 31533839 = 31534072
239 + 31533833 = 31534072
281 + 31533791 = 31534072
431 + 31533641 = 31534072
461 + 31533611 = 31534072

Showing the first eight; more decompositions exist.
