Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185788, here are decompositions:

41 + 185747 = 185788
89 + 185699 = 185788
107 + 185681 = 185788
137 + 185651 = 185788
167 + 185621 = 185788
257 + 185531 = 185788
269 + 185519 = 185788
311 + 185477 = 185788

Showing the first eight; more decompositions exist.
