Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184812, here are decompositions:

59 + 184753 = 184812
79 + 184733 = 184812
101 + 184711 = 184812
109 + 184703 = 184812
163 + 184649 = 184812
179 + 184633 = 184812
181 + 184631 = 184812
241 + 184571 = 184812

Showing the first eight; more decompositions exist.
