Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537612, here are decompositions:

3 + 31537609 = 31537612
53 + 31537559 = 31537612
131 + 31537481 = 31537612
179 + 31537433 = 31537612
383 + 31537229 = 31537612
389 + 31537223 = 31537612
461 + 31537151 = 31537612
479 + 31537133 = 31537612

Showing the first eight; more decompositions exist.
