Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611562, here are decompositions:

23 + 31611539 = 31611562
53 + 31611509 = 31611562
89 + 31611473 = 31611562
233 + 31611329 = 31611562
239 + 31611323 = 31611562
251 + 31611311 = 31611562
263 + 31611299 = 31611562
449 + 31611113 = 31611562

Showing the first eight; more decompositions exist.
