Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542560, here are decompositions:

3 + 33542557 = 33542560
71 + 33542489 = 33542560
83 + 33542477 = 33542560
197 + 33542363 = 33542560
239 + 33542321 = 33542560
263 + 33542297 = 33542560
449 + 33542111 = 33542560
509 + 33542051 = 33542560

Showing the first eight; more decompositions exist.
