Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739222, here are decompositions:

13 + 8739209 = 8739222
29 + 8739193 = 8739222
53 + 8739169 = 8739222
59 + 8739163 = 8739222
103 + 8739119 = 8739222
109 + 8739113 = 8739222
199 + 8739023 = 8739222
293 + 8738929 = 8739222

Showing the first eight; more decompositions exist.
