Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620198, here are decompositions:

11 + 8620187 = 8620198
47 + 8620151 = 8620198
89 + 8620109 = 8620198
149 + 8620049 = 8620198
401 + 8619797 = 8620198
479 + 8619719 = 8620198
647 + 8619551 = 8620198
659 + 8619539 = 8620198

Showing the first eight; more decompositions exist.
