Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528618, here are decompositions:

7 + 528611 = 528618
59 + 528559 = 528618
107 + 528511 = 528618
109 + 528509 = 528618
127 + 528491 = 528618
131 + 528487 = 528618
149 + 528469 = 528618
199 + 528419 = 528618

Showing the first eight; more decompositions exist.
