Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634820, here are decompositions:

17 + 8634803 = 8634820
53 + 8634767 = 8634820
59 + 8634761 = 8634820
107 + 8634713 = 8634820
149 + 8634671 = 8634820
191 + 8634629 = 8634820
239 + 8634581 = 8634820
263 + 8634557 = 8634820

Showing the first eight; more decompositions exist.
