Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743786, here are decompositions:

17 + 8743769 = 8743786
53 + 8743733 = 8743786
113 + 8743673 = 8743786
197 + 8743589 = 8743786
239 + 8743547 = 8743786
419 + 8743367 = 8743786
509 + 8743277 = 8743786
617 + 8743169 = 8743786

Showing the first eight; more decompositions exist.
