Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587990, here are decompositions:

97 + 33587893 = 33587990
127 + 33587863 = 33587990
157 + 33587833 = 33587990
181 + 33587809 = 33587990
199 + 33587791 = 33587990
229 + 33587761 = 33587990
283 + 33587707 = 33587990
307 + 33587683 = 33587990

Showing the first eight; more decompositions exist.
