Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506778, here are decompositions:

5 + 506773 = 506778
47 + 506731 = 506778
79 + 506699 = 506778
89 + 506689 = 506778
131 + 506647 = 506778
149 + 506629 = 506778
179 + 506599 = 506778
227 + 506551 = 506778

Showing the first eight; more decompositions exist.
