Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623574, here are decompositions:

53 + 31623521 = 31623574
83 + 31623491 = 31623574
113 + 31623461 = 31623574
131 + 31623443 = 31623574
197 + 31623377 = 31623574
317 + 31623257 = 31623574
401 + 31623173 = 31623574
461 + 31623113 = 31623574

Showing the first eight; more decompositions exist.
