Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607532, here are decompositions:

29 + 31607503 = 31607532
43 + 31607489 = 31607532
59 + 31607473 = 31607532
71 + 31607461 = 31607532
83 + 31607449 = 31607532
109 + 31607423 = 31607532
191 + 31607341 = 31607532
223 + 31607309 = 31607532

Showing the first eight; more decompositions exist.
