Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80620, here are decompositions:

17 + 80603 = 80620
53 + 80567 = 80620
83 + 80537 = 80620
107 + 80513 = 80620
131 + 80489 = 80620
149 + 80471 = 80620
173 + 80447 = 80620
191 + 80429 = 80620

Showing the first eight; more decompositions exist.
