Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623562, here are decompositions:

41 + 31623521 = 31623562
53 + 31623509 = 31623562
71 + 31623491 = 31623562
83 + 31623479 = 31623562
101 + 31623461 = 31623562
353 + 31623209 = 31623562
389 + 31623173 = 31623562
449 + 31623113 = 31623562

Showing the first eight; more decompositions exist.
