Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587430, here are decompositions:

13 + 33587417 = 33587430
29 + 33587401 = 33587430
59 + 33587371 = 33587430
67 + 33587363 = 33587430
73 + 33587357 = 33587430
83 + 33587347 = 33587430
109 + 33587321 = 33587430
127 + 33587303 = 33587430

Showing the first eight; more decompositions exist.
