Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739372, here are decompositions:

13 + 8739359 = 8739372
23 + 8739349 = 8739372
41 + 8739331 = 8739372
73 + 8739299 = 8739372
163 + 8739209 = 8739372
179 + 8739193 = 8739372
293 + 8739079 = 8739372
349 + 8739023 = 8739372

Showing the first eight; more decompositions exist.
