Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179786, here are decompositions:

7 + 179779 = 179786
37 + 179749 = 179786
43 + 179743 = 179786
67 + 179719 = 179786
97 + 179689 = 179786
127 + 179659 = 179786
163 + 179623 = 179786
193 + 179593 = 179786

Showing the first eight; more decompositions exist.
