Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587378, here are decompositions:

7 + 33587371 = 33587378
31 + 33587347 = 33587378
67 + 33587311 = 33587378
127 + 33587251 = 33587378
367 + 33587011 = 33587378
421 + 33586957 = 33587378
439 + 33586939 = 33587378
457 + 33586921 = 33587378

Showing the first eight; more decompositions exist.
