Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587438, here are decompositions:

37 + 33587401 = 33587438
67 + 33587371 = 33587438
127 + 33587311 = 33587438
151 + 33587287 = 33587438
229 + 33587209 = 33587438
277 + 33587161 = 33587438
349 + 33587089 = 33587438
499 + 33586939 = 33587438

Showing the first eight; more decompositions exist.
