Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675920, here are decompositions:

17 + 8675903 = 8675920
41 + 8675879 = 8675920
59 + 8675861 = 8675920
107 + 8675813 = 8675920
269 + 8675651 = 8675920
347 + 8675573 = 8675920
479 + 8675441 = 8675920
521 + 8675399 = 8675920

Showing the first eight; more decompositions exist.
