Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607624, here are decompositions:

43 + 31607581 = 31607624
73 + 31607551 = 31607624
151 + 31607473 = 31607624
163 + 31607461 = 31607624
283 + 31607341 = 31607624
331 + 31607293 = 31607624
397 + 31607227 = 31607624
487 + 31607137 = 31607624

Showing the first eight; more decompositions exist.
