Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637806, here are decompositions:

19 + 8637787 = 8637806
109 + 8637697 = 8637806
139 + 8637667 = 8637806
283 + 8637523 = 8637806
313 + 8637493 = 8637806
379 + 8637427 = 8637806
433 + 8637373 = 8637806
487 + 8637319 = 8637806

Showing the first eight; more decompositions exist.
