Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152620, here are decompositions:

3 + 152617 = 152620
23 + 152597 = 152620
53 + 152567 = 152620
89 + 152531 = 152620
101 + 152519 = 152620
179 + 152441 = 152620
191 + 152429 = 152620
197 + 152423 = 152620

Showing the first eight; more decompositions exist.
