Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756820, here are decompositions:

13 + 8756807 = 8756820
31 + 8756789 = 8756820
113 + 8756707 = 8756820
131 + 8756689 = 8756820
151 + 8756669 = 8756820
167 + 8756653 = 8756820
197 + 8756623 = 8756820
211 + 8756609 = 8756820

Showing the first eight; more decompositions exist.
