Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601532, here are decompositions:

5 + 31601527 = 31601532
19 + 31601513 = 31601532
23 + 31601509 = 31601532
43 + 31601489 = 31601532
59 + 31601473 = 31601532
139 + 31601393 = 31601532
173 + 31601359 = 31601532
191 + 31601341 = 31601532

Showing the first eight; more decompositions exist.
