Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018524, here are decompositions:

11 + 1018513 = 1018524
47 + 1018477 = 1018524
53 + 1018471 = 1018524
103 + 1018421 = 1018524
113 + 1018411 = 1018524
167 + 1018357 = 1018524
211 + 1018313 = 1018524
223 + 1018301 = 1018524

Showing the first eight; more decompositions exist.
