Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587418, here are decompositions:

17 + 33587401 = 33587418
47 + 33587371 = 33587418
61 + 33587357 = 33587418
71 + 33587347 = 33587418
79 + 33587339 = 33587418
97 + 33587321 = 33587418
107 + 33587311 = 33587418
131 + 33587287 = 33587418

Showing the first eight; more decompositions exist.
