Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742904, here are decompositions:

17 + 8742887 = 8742904
47 + 8742857 = 8742904
83 + 8742821 = 8742904
227 + 8742677 = 8742904
251 + 8742653 = 8742904
281 + 8742623 = 8742904
353 + 8742551 = 8742904
503 + 8742401 = 8742904

Showing the first eight; more decompositions exist.
