Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623626, here are decompositions:

3 + 31623623 = 31623626
19 + 31623607 = 31623626
37 + 31623589 = 31623626
103 + 31623523 = 31623626
127 + 31623499 = 31623626
283 + 31623343 = 31623626
457 + 31623169 = 31623626
733 + 31622893 = 31623626

Showing the first eight; more decompositions exist.
