Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619048, here are decompositions:

7 + 31619041 = 31619048
31 + 31619017 = 31619048
67 + 31618981 = 31619048
151 + 31618897 = 31619048
157 + 31618891 = 31619048
199 + 31618849 = 31619048
229 + 31618819 = 31619048
271 + 31618777 = 31619048

Showing the first eight; more decompositions exist.
