Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611496, here are decompositions:

23 + 31611473 = 31611496
29 + 31611467 = 31611496
167 + 31611329 = 31611496
173 + 31611323 = 31611496
197 + 31611299 = 31611496
359 + 31611137 = 31611496
383 + 31611113 = 31611496
467 + 31611029 = 31611496

Showing the first eight; more decompositions exist.
