Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031530, here are decompositions:

23 + 1031507 = 1031530
41 + 1031489 = 1031530
47 + 1031483 = 1031530
53 + 1031477 = 1031530
83 + 1031447 = 1031530
107 + 1031423 = 1031530
131 + 1031399 = 1031530
173 + 1031357 = 1031530

Showing the first eight; more decompositions exist.
