Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620202, here are decompositions:

13 + 8620189 = 8620202
43 + 8620159 = 8620202
61 + 8620141 = 8620202
139 + 8620063 = 8620202
541 + 8619661 = 8620202
601 + 8619601 = 8620202
691 + 8619511 = 8620202
733 + 8619469 = 8620202

Showing the first eight; more decompositions exist.
