Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178512, here are decompositions:

11 + 178501 = 178512
23 + 178489 = 178512
31 + 178481 = 178512
43 + 178469 = 178512
71 + 178441 = 178512
73 + 178439 = 178512
109 + 178403 = 178512
151 + 178361 = 178512

Showing the first eight; more decompositions exist.
