Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678740, here are decompositions:

41 + 8678699 = 8678740
47 + 8678693 = 8678740
71 + 8678669 = 8678740
101 + 8678639 = 8678740
137 + 8678603 = 8678740
233 + 8678507 = 8678740
293 + 8678447 = 8678740
347 + 8678393 = 8678740

Showing the first eight; more decompositions exist.
