Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33532640, here are decompositions:

13 + 33532627 = 33532640
19 + 33532621 = 33532640
61 + 33532579 = 33532640
73 + 33532567 = 33532640
103 + 33532537 = 33532640
151 + 33532489 = 33532640
277 + 33532363 = 33532640
283 + 33532357 = 33532640

Showing the first eight; more decompositions exist.
