Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525618, here are decompositions:

11 + 525607 = 525618
19 + 525599 = 525618
47 + 525571 = 525618
89 + 525529 = 525618
101 + 525517 = 525618
127 + 525491 = 525618
151 + 525467 = 525618
157 + 525461 = 525618

Showing the first eight; more decompositions exist.
