Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500688, here are decompositions:

11 + 500677 = 500688
17 + 500671 = 500688
59 + 500629 = 500688
101 + 500587 = 500688
109 + 500579 = 500688
179 + 500509 = 500688
229 + 500459 = 500688
257 + 500431 = 500688

Showing the first eight; more decompositions exist.
