Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742814, here are decompositions:

137 + 8742677 = 8742814
191 + 8742623 = 8742814
263 + 8742551 = 8742814
317 + 8742497 = 8742814
461 + 8742353 = 8742814
467 + 8742347 = 8742814
617 + 8742197 = 8742814
653 + 8742161 = 8742814

Showing the first eight; more decompositions exist.
