Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623544, here are decompositions:

23 + 31623521 = 31623544
47 + 31623497 = 31623544
53 + 31623491 = 31623544
83 + 31623461 = 31623544
101 + 31623443 = 31623544
167 + 31623377 = 31623544
431 + 31623113 = 31623544
503 + 31623041 = 31623544

Showing the first eight; more decompositions exist.
