Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623622, here are decompositions:

5 + 31623617 = 31623622
101 + 31623521 = 31623622
113 + 31623509 = 31623622
131 + 31623491 = 31623622
179 + 31623443 = 31623622
449 + 31623173 = 31623622
509 + 31623113 = 31623622
599 + 31623023 = 31623622

Showing the first eight; more decompositions exist.
