Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173620, here are decompositions:

3 + 173617 = 173620
47 + 173573 = 173620
59 + 173561 = 173620
71 + 173549 = 173620
89 + 173531 = 173620
137 + 173483 = 173620
191 + 173429 = 173620
263 + 173357 = 173620

Showing the first eight; more decompositions exist.
