Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487912, here are decompositions:

5 + 33487907 = 33487912
11 + 33487901 = 33487912
53 + 33487859 = 33487912
179 + 33487733 = 33487912
281 + 33487631 = 33487912
401 + 33487511 = 33487912
461 + 33487451 = 33487912
569 + 33487343 = 33487912

Showing the first eight; more decompositions exist.
