Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180786, here are decompositions:

7 + 180779 = 180786
13 + 180773 = 180786
37 + 180749 = 180786
107 + 180679 = 180786
139 + 180647 = 180786
157 + 180629 = 180786
163 + 180623 = 180786
223 + 180563 = 180786

Showing the first eight; more decompositions exist.
