Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739220, here are decompositions:

11 + 8739209 = 8739220
23 + 8739197 = 8739220
53 + 8739167 = 8739220
101 + 8739119 = 8739220
107 + 8739113 = 8739220
167 + 8739053 = 8739220
197 + 8739023 = 8739220
257 + 8738963 = 8739220

Showing the first eight; more decompositions exist.
