Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018512, here are decompositions:

23 + 1018489 = 1018512
41 + 1018471 = 1018512
73 + 1018439 = 1018512
83 + 1018429 = 1018512
101 + 1018411 = 1018512
199 + 1018313 = 1018512
211 + 1018301 = 1018512
241 + 1018271 = 1018512

Showing the first eight; more decompositions exist.
