Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515990, here are decompositions:

19 + 33515971 = 33515990
73 + 33515917 = 33515990
97 + 33515893 = 33515990
127 + 33515863 = 33515990
271 + 33515719 = 33515990
283 + 33515707 = 33515990
373 + 33515617 = 33515990
397 + 33515593 = 33515990

Showing the first eight; more decompositions exist.
