Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507666, here are decompositions:

59 + 507607 = 507666
67 + 507599 = 507666
73 + 507593 = 507666
109 + 507557 = 507666
163 + 507503 = 507666
167 + 507499 = 507666
283 + 507383 = 507666
307 + 507359 = 507666

Showing the first eight; more decompositions exist.
