Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739406, here are decompositions:

17 + 8739389 = 8739406
47 + 8739359 = 8739406
107 + 8739299 = 8739406
197 + 8739209 = 8739406
239 + 8739167 = 8739406
293 + 8739113 = 8739406
353 + 8739053 = 8739406
383 + 8739023 = 8739406

Showing the first eight; more decompositions exist.
