Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700620, here are decompositions:

31 + 8700589 = 8700620
73 + 8700547 = 8700620
109 + 8700511 = 8700620
163 + 8700457 = 8700620
199 + 8700421 = 8700620
337 + 8700283 = 8700620
367 + 8700253 = 8700620
499 + 8700121 = 8700620

Showing the first eight; more decompositions exist.
