Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018452, here are decompositions:

5 + 1018447 = 1018452
13 + 1018439 = 1018452
23 + 1018429 = 1018452
31 + 1018421 = 1018452
41 + 1018411 = 1018452
139 + 1018313 = 1018452
151 + 1018301 = 1018452
181 + 1018271 = 1018452

Showing the first eight; more decompositions exist.
