Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185072, here are decompositions:

3 + 185069 = 185072
73 + 184999 = 185072
79 + 184993 = 185072
103 + 184969 = 185072
193 + 184879 = 185072
229 + 184843 = 185072
241 + 184831 = 185072
379 + 184693 = 185072

Showing the first eight; more decompositions exist.
