Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507640, here are decompositions:

41 + 507599 = 507640
47 + 507593 = 507640
83 + 507557 = 507640
137 + 507503 = 507640
149 + 507491 = 507640
179 + 507461 = 507640
239 + 507401 = 507640
257 + 507383 = 507640

Showing the first eight; more decompositions exist.
