Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179742, here are decompositions:

5 + 179737 = 179742
23 + 179719 = 179742
53 + 179689 = 179742
71 + 179671 = 179742
83 + 179659 = 179742
109 + 179633 = 179742
139 + 179603 = 179742
149 + 179593 = 179742

Showing the first eight; more decompositions exist.
