Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33532780, here are decompositions:

23 + 33532757 = 33532780
107 + 33532673 = 33532780
179 + 33532601 = 33532780
311 + 33532469 = 33532780
353 + 33532427 = 33532780
389 + 33532391 = 33532780
401 + 33532379 = 33532780
431 + 33532349 = 33532780

Showing the first eight; more decompositions exist.
