Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567162, here are decompositions:

5 + 31567157 = 31567162
71 + 31567091 = 31567162
113 + 31567049 = 31567162
251 + 31566911 = 31567162
359 + 31566803 = 31567162
449 + 31566713 = 31567162
503 + 31566659 = 31567162
563 + 31566599 = 31567162

Showing the first eight; more decompositions exist.
