Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730650, here are decompositions:

31 + 8730619 = 8730650
43 + 8730607 = 8730650
67 + 8730583 = 8730650
73 + 8730577 = 8730650
139 + 8730511 = 8730650
163 + 8730487 = 8730650
307 + 8730343 = 8730650
367 + 8730283 = 8730650

Showing the first eight; more decompositions exist.
