Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606624, here are decompositions:

41 + 31606583 = 31606624
83 + 31606541 = 31606624
107 + 31606517 = 31606624
131 + 31606493 = 31606624
227 + 31606397 = 31606624
251 + 31606373 = 31606624
281 + 31606343 = 31606624
293 + 31606331 = 31606624

Showing the first eight; more decompositions exist.
