Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1033640, here are decompositions:

37 + 1033603 = 1033640
73 + 1033567 = 1033640
103 + 1033537 = 1033640
151 + 1033489 = 1033640
199 + 1033441 = 1033640
271 + 1033369 = 1033640
277 + 1033363 = 1033640
331 + 1033309 = 1033640

Showing the first eight; more decompositions exist.
