Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607832, here are decompositions:

41 + 31607791 = 31607832
43 + 31607789 = 31607832
149 + 31607683 = 31607832
233 + 31607599 = 31607832
251 + 31607581 = 31607832
281 + 31607551 = 31607832
359 + 31607473 = 31607832
383 + 31607449 = 31607832

Showing the first eight; more decompositions exist.
