Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611502, here are decompositions:

29 + 31611473 = 31611502
173 + 31611329 = 31611502
179 + 31611323 = 31611502
191 + 31611311 = 31611502
389 + 31611113 = 31611502
401 + 31611101 = 31611502
479 + 31611023 = 31611502
491 + 31611011 = 31611502

Showing the first eight; more decompositions exist.
