Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746820, here are decompositions:

7 + 8746813 = 8746820
13 + 8746807 = 8746820
67 + 8746753 = 8746820
97 + 8746723 = 8746820
211 + 8746609 = 8746820
307 + 8746513 = 8746820
367 + 8746453 = 8746820
373 + 8746447 = 8746820

Showing the first eight; more decompositions exist.
