Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537012, here are decompositions:

11 + 31537001 = 31537012
29 + 31536983 = 31537012
53 + 31536959 = 31537012
149 + 31536863 = 31537012
191 + 31536821 = 31537012
239 + 31536773 = 31537012
281 + 31536731 = 31537012
293 + 31536719 = 31537012

Showing the first eight; more decompositions exist.
