Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526856, here are decompositions:

37 + 31526819 = 31526856
47 + 31526809 = 31526856
79 + 31526777 = 31526856
83 + 31526773 = 31526856
103 + 31526753 = 31526856
107 + 31526749 = 31526856
167 + 31526689 = 31526856
223 + 31526633 = 31526856

Showing the first eight; more decompositions exist.
