Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84620, here are decompositions:

31 + 84589 = 84620
61 + 84559 = 84620
97 + 84523 = 84620
139 + 84481 = 84620
157 + 84463 = 84620
163 + 84457 = 84620
199 + 84421 = 84620
229 + 84391 = 84620

Showing the first eight; more decompositions exist.
