Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180846, here are decompositions:

47 + 180799 = 180846
53 + 180793 = 180846
67 + 180779 = 180846
73 + 180773 = 180846
97 + 180749 = 180846
167 + 180679 = 180846
179 + 180667 = 180846
199 + 180647 = 180846

Showing the first eight; more decompositions exist.
