Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623532, here are decompositions:

11 + 31623521 = 31623532
23 + 31623509 = 31623532
41 + 31623491 = 31623532
53 + 31623479 = 31623532
71 + 31623461 = 31623532
89 + 31623443 = 31623532
359 + 31623173 = 31623532
419 + 31623113 = 31623532

Showing the first eight; more decompositions exist.
