Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678288, here are decompositions:

109 + 8678179 = 8678288
127 + 8678161 = 8678288
139 + 8678149 = 8678288
277 + 8678011 = 8678288
337 + 8677951 = 8678288
397 + 8677891 = 8678288
607 + 8677681 = 8678288
811 + 8677477 = 8678288

Showing the first eight; more decompositions exist.
