Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617622, here are decompositions:

59 + 31617563 = 31617622
89 + 31617533 = 31617622
173 + 31617449 = 31617622
191 + 31617431 = 31617622
251 + 31617371 = 31617622
293 + 31617329 = 31617622
353 + 31617269 = 31617622
383 + 31617239 = 31617622

Showing the first eight; more decompositions exist.
