Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507878, here are decompositions:

97 + 507781 = 507878
181 + 507697 = 507878
211 + 507667 = 507878
271 + 507607 = 507878
307 + 507571 = 507878
379 + 507499 = 507878
457 + 507421 = 507878
577 + 507301 = 507878

Showing the first eight; more decompositions exist.
