Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739280, here are decompositions:

71 + 8739209 = 8739280
83 + 8739197 = 8739280
113 + 8739167 = 8739280
167 + 8739113 = 8739280
227 + 8739053 = 8739280
257 + 8739023 = 8739280
317 + 8738963 = 8739280
443 + 8738837 = 8739280

Showing the first eight; more decompositions exist.
