Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620622, here are decompositions:

19 + 8620603 = 8620622
79 + 8620543 = 8620622
193 + 8620429 = 8620622
229 + 8620393 = 8620622
433 + 8620189 = 8620622
463 + 8620159 = 8620622
739 + 8619883 = 8620622
811 + 8619811 = 8620622

Showing the first eight; more decompositions exist.
