Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487970, here are decompositions:

67 + 33487903 = 33487970
151 + 33487819 = 33487970
157 + 33487813 = 33487970
199 + 33487771 = 33487970
211 + 33487759 = 33487970
331 + 33487639 = 33487970
349 + 33487621 = 33487970
379 + 33487591 = 33487970

Showing the first eight; more decompositions exist.
