Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738646, here are decompositions:

5 + 8738641 = 8738646
67 + 8738579 = 8738646
79 + 8738567 = 8738646
107 + 8738539 = 8738646
113 + 8738533 = 8738646
139 + 8738507 = 8738646
173 + 8738473 = 8738646
197 + 8738449 = 8738646

Showing the first eight; more decompositions exist.
