Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623006, here are decompositions:

47 + 31622959 = 31623006
59 + 31622947 = 31623006
67 + 31622939 = 31623006
73 + 31622933 = 31623006
83 + 31622923 = 31623006
113 + 31622893 = 31623006
197 + 31622809 = 31623006
227 + 31622779 = 31623006

Showing the first eight; more decompositions exist.
