Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617602, here are decompositions:

19 + 31617583 = 31617602
43 + 31617559 = 31617602
73 + 31617529 = 31617602
109 + 31617493 = 31617602
193 + 31617409 = 31617602
199 + 31617403 = 31617602
223 + 31617379 = 31617602
229 + 31617373 = 31617602

Showing the first eight; more decompositions exist.
