Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743870, here are decompositions:

17 + 8743853 = 8743870
53 + 8743817 = 8743870
101 + 8743769 = 8743870
137 + 8743733 = 8743870
197 + 8743673 = 8743870
281 + 8743589 = 8743870
449 + 8743421 = 8743870
461 + 8743409 = 8743870

Showing the first eight; more decompositions exist.
