Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623796, here are decompositions:

89 + 31623707 = 31623796
173 + 31623623 = 31623796
179 + 31623617 = 31623796
317 + 31623479 = 31623796
353 + 31623443 = 31623796
419 + 31623377 = 31623796
587 + 31623209 = 31623796
683 + 31623113 = 31623796

Showing the first eight; more decompositions exist.
