Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626820, here are decompositions:

19 + 8626801 = 8626820
43 + 8626777 = 8626820
73 + 8626747 = 8626820
151 + 8626669 = 8626820
199 + 8626621 = 8626820
271 + 8626549 = 8626820
313 + 8626507 = 8626820
523 + 8626297 = 8626820

Showing the first eight; more decompositions exist.
