Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739638, here are decompositions:

31 + 8739607 = 8739638
109 + 8739529 = 8739638
139 + 8739499 = 8739638
157 + 8739481 = 8739638
241 + 8739397 = 8739638
307 + 8739331 = 8739638
541 + 8739097 = 8739638
631 + 8739007 = 8739638

Showing the first eight; more decompositions exist.
