Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518642, here are decompositions:

19 + 33518623 = 33518642
103 + 33518539 = 33518642
151 + 33518491 = 33518642
193 + 33518449 = 33518642
349 + 33518293 = 33518642
373 + 33518269 = 33518642
433 + 33518209 = 33518642
523 + 33518119 = 33518642

Showing the first eight; more decompositions exist.
