Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756920, here are decompositions:

23 + 8756897 = 8756920
83 + 8756837 = 8756920
113 + 8756807 = 8756920
131 + 8756789 = 8756920
149 + 8756771 = 8756920
233 + 8756687 = 8756920
251 + 8756669 = 8756920
311 + 8756609 = 8756920

Showing the first eight; more decompositions exist.
