Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616526, here are decompositions:

5 + 31616521 = 31616526
17 + 31616509 = 31616526
47 + 31616479 = 31616526
103 + 31616423 = 31616526
107 + 31616419 = 31616526
157 + 31616369 = 31616526
163 + 31616363 = 31616526
167 + 31616359 = 31616526

Showing the first eight; more decompositions exist.
