Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623048, here are decompositions:

7 + 31623041 = 31623048
89 + 31622959 = 31623048
97 + 31622951 = 31623048
101 + 31622947 = 31623048
109 + 31622939 = 31623048
167 + 31622881 = 31623048
211 + 31622837 = 31623048
239 + 31622809 = 31623048

Showing the first eight; more decompositions exist.
