Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743780, here are decompositions:

11 + 8743769 = 8743780
47 + 8743733 = 8743780
107 + 8743673 = 8743780
191 + 8743589 = 8743780
197 + 8743583 = 8743780
233 + 8743547 = 8743780
281 + 8743499 = 8743780
359 + 8743421 = 8743780

Showing the first eight; more decompositions exist.
