Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488390, here are decompositions:

37 + 33488353 = 33488390
79 + 33488311 = 33488390
109 + 33488281 = 33488390
223 + 33488167 = 33488390
283 + 33488107 = 33488390
349 + 33488041 = 33488390
421 + 33487969 = 33488390
487 + 33487903 = 33488390

Showing the first eight; more decompositions exist.
