Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587180, here are decompositions:

7 + 33587173 = 33587180
19 + 33587161 = 33587180
37 + 33587143 = 33587180
223 + 33586957 = 33587180
241 + 33586939 = 33587180
283 + 33586897 = 33587180
313 + 33586867 = 33587180
499 + 33586681 = 33587180

Showing the first eight; more decompositions exist.
