Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987620, here are decompositions:

13 + 987607 = 987620
61 + 987559 = 987620
79 + 987541 = 987620
97 + 987523 = 987620
157 + 987463 = 987620
163 + 987457 = 987620
229 + 987391 = 987620
307 + 987313 = 987620

Showing the first eight; more decompositions exist.
