Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179722, here are decompositions:

3 + 179719 = 179722
5 + 179717 = 179722
29 + 179693 = 179722
71 + 179651 = 179722
89 + 179633 = 179722
131 + 179591 = 179722
149 + 179573 = 179722
173 + 179549 = 179722

Showing the first eight; more decompositions exist.
