Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739878, here are decompositions:

67 + 8739811 = 8739878
109 + 8739769 = 8739878
139 + 8739739 = 8739878
157 + 8739721 = 8739878
211 + 8739667 = 8739878
241 + 8739637 = 8739878
271 + 8739607 = 8739878
349 + 8739529 = 8739878

Showing the first eight; more decompositions exist.
