Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743220, here are decompositions:

7 + 8743213 = 8743220
193 + 8743027 = 8743220
223 + 8742997 = 8743220
373 + 8742847 = 8743220
433 + 8742787 = 8743220
547 + 8742673 = 8743220
643 + 8742577 = 8743220
691 + 8742529 = 8743220

Showing the first eight; more decompositions exist.
