Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622920, here are decompositions:

37 + 8622883 = 8622920
43 + 8622877 = 8622920
67 + 8622853 = 8622920
73 + 8622847 = 8622920
79 + 8622841 = 8622920
109 + 8622811 = 8622920
127 + 8622793 = 8622920
139 + 8622781 = 8622920

Showing the first eight; more decompositions exist.
