Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587380, here are decompositions:

17 + 33587363 = 33587380
23 + 33587357 = 33587380
41 + 33587339 = 33587380
59 + 33587321 = 33587380
269 + 33587111 = 33587380
383 + 33586997 = 33587380
389 + 33586991 = 33587380
443 + 33586937 = 33587380

Showing the first eight; more decompositions exist.
