Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742758, here are decompositions:

19 + 8742739 = 8742758
181 + 8742577 = 8742758
229 + 8742529 = 8742758
337 + 8742421 = 8742758
379 + 8742379 = 8742758
499 + 8742259 = 8742758
571 + 8742187 = 8742758
601 + 8742157 = 8742758

Showing the first eight; more decompositions exist.
