Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739392, here are decompositions:

3 + 8739389 = 8739392
43 + 8739349 = 8739392
61 + 8739331 = 8739392
199 + 8739193 = 8739392
223 + 8739169 = 8739392
229 + 8739163 = 8739392
313 + 8739079 = 8739392
463 + 8738929 = 8739392

Showing the first eight; more decompositions exist.
