Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742986, here are decompositions:

13 + 8742973 = 8742986
67 + 8742919 = 8742986
139 + 8742847 = 8742986
199 + 8742787 = 8742986
313 + 8742673 = 8742986
349 + 8742637 = 8742986
409 + 8742577 = 8742986
457 + 8742529 = 8742986

Showing the first eight; more decompositions exist.
