Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613962, here are decompositions:

101 + 31613861 = 31613962
179 + 31613783 = 31613962
293 + 31613669 = 31613962
383 + 31613579 = 31613962
449 + 31613513 = 31613962
521 + 31613441 = 31613962
563 + 31613399 = 31613962
719 + 31613243 = 31613962

Showing the first eight; more decompositions exist.
