Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611508, here are decompositions:

41 + 31611467 = 31611508
167 + 31611341 = 31611508
179 + 31611329 = 31611508
197 + 31611311 = 31611508
419 + 31611089 = 31611508
479 + 31611029 = 31611508
491 + 31611017 = 31611508
641 + 31610867 = 31611508

Showing the first eight; more decompositions exist.
