Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623412, here are decompositions:

239 + 31623173 = 31623412
389 + 31623023 = 31623412
461 + 31622951 = 31623412
479 + 31622933 = 31623412
683 + 31622729 = 31623412
719 + 31622693 = 31623412
983 + 31622429 = 31623412
1223 + 31622189 = 31623412

Showing the first eight; more decompositions exist.
