Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680790, here are decompositions:

37 + 8680753 = 8680790
67 + 8680723 = 8680790
73 + 8680717 = 8680790
277 + 8680513 = 8680790
373 + 8680417 = 8680790
421 + 8680369 = 8680790
463 + 8680327 = 8680790
487 + 8680303 = 8680790

Showing the first eight; more decompositions exist.
