Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500660, here are decompositions:

31 + 500629 = 500660
73 + 500587 = 500660
151 + 500509 = 500660
229 + 500431 = 500660
271 + 500389 = 500660
373 + 500287 = 500660
421 + 500239 = 500660
463 + 500197 = 500660

Showing the first eight; more decompositions exist.
