Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726920, here are decompositions:

3 + 8726917 = 8726920
47 + 8726873 = 8726920
71 + 8726849 = 8726920
131 + 8726789 = 8726920
197 + 8726723 = 8726920
233 + 8726687 = 8726920
347 + 8726573 = 8726920
557 + 8726363 = 8726920

Showing the first eight; more decompositions exist.
