Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739810, here are decompositions:

7 + 8739803 = 8739810
41 + 8739769 = 8739810
43 + 8739767 = 8739810
61 + 8739749 = 8739810
71 + 8739739 = 8739810
89 + 8739721 = 8739810
97 + 8739713 = 8739810
137 + 8739673 = 8739810

Showing the first eight; more decompositions exist.
