Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607194, here are decompositions:

41 + 31607153 = 31607194
107 + 31607087 = 31607194
197 + 31606997 = 31607194
251 + 31606943 = 31607194
263 + 31606931 = 31607194
347 + 31606847 = 31607194
383 + 31606811 = 31607194
467 + 31606727 = 31607194

Showing the first eight; more decompositions exist.
