Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487636, here are decompositions:

29 + 487607 = 487636
47 + 487589 = 487636
167 + 487469 = 487636
173 + 487463 = 487636
179 + 487457 = 487636
239 + 487397 = 487636
353 + 487283 = 487636
389 + 487247 = 487636

Showing the first eight; more decompositions exist.
