Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626584, here are decompositions:

13 + 31626571 = 31626584
37 + 31626547 = 31626584
103 + 31626481 = 31626584
163 + 31626421 = 31626584
337 + 31626247 = 31626584
631 + 31625953 = 31626584
673 + 31625911 = 31626584
811 + 31625773 = 31626584

Showing the first eight; more decompositions exist.
