Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623586, here are decompositions:

89 + 31623497 = 31623586
107 + 31623479 = 31623586
419 + 31623167 = 31623586
563 + 31623023 = 31623586
647 + 31622939 = 31623586
653 + 31622933 = 31623586
809 + 31622777 = 31623586
857 + 31622729 = 31623586

Showing the first eight; more decompositions exist.
