Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617832, here are decompositions:

5 + 31617827 = 31617832
173 + 31617659 = 31617832
269 + 31617563 = 31617832
383 + 31617449 = 31617832
401 + 31617431 = 31617832
419 + 31617413 = 31617832
461 + 31617371 = 31617832
503 + 31617329 = 31617832

Showing the first eight; more decompositions exist.
