Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623654, here are decompositions:

31 + 31623623 = 31623654
37 + 31623617 = 31623654
47 + 31623607 = 31623654
131 + 31623523 = 31623654
157 + 31623497 = 31623654
163 + 31623491 = 31623654
173 + 31623481 = 31623654
193 + 31623461 = 31623654

Showing the first eight; more decompositions exist.
