Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678530, here are decompositions:

11 + 8678519 = 8678530
23 + 8678507 = 8678530
83 + 8678447 = 8678530
131 + 8678399 = 8678530
137 + 8678393 = 8678530
167 + 8678363 = 8678530
191 + 8678339 = 8678530
197 + 8678333 = 8678530

Showing the first eight; more decompositions exist.
