Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530642, here are decompositions:

73 + 33530569 = 33530642
151 + 33530491 = 33530642
193 + 33530449 = 33530642
241 + 33530401 = 33530642
283 + 33530359 = 33530642
463 + 33530179 = 33530642
571 + 33530071 = 33530642
619 + 33530023 = 33530642

Showing the first eight; more decompositions exist.
