Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611532, here are decompositions:

5 + 31611527 = 31611532
23 + 31611509 = 31611532
59 + 31611473 = 31611532
191 + 31611341 = 31611532
233 + 31611299 = 31611532
419 + 31611113 = 31611532
431 + 31611101 = 31611532
443 + 31611089 = 31611532

Showing the first eight; more decompositions exist.
