Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720926, here are decompositions:

89 + 8720837 = 8720926
107 + 8720819 = 8720926
197 + 8720729 = 8720926
233 + 8720693 = 8720926
239 + 8720687 = 8720926
443 + 8720483 = 8720926
449 + 8720477 = 8720926
479 + 8720447 = 8720926

Showing the first eight; more decompositions exist.
