Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182788, here are decompositions:

41 + 182747 = 182788
101 + 182687 = 182788
107 + 182681 = 182788
131 + 182657 = 182788
149 + 182639 = 182788
227 + 182561 = 182788
239 + 182549 = 182788
251 + 182537 = 182788

Showing the first eight; more decompositions exist.
