Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742926, here are decompositions:

7 + 8742919 = 8742926
79 + 8742847 = 8742926
109 + 8742817 = 8742926
139 + 8742787 = 8742926
349 + 8742577 = 8742926
397 + 8742529 = 8742926
433 + 8742493 = 8742926
457 + 8742469 = 8742926

Showing the first eight; more decompositions exist.
