Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725372, here are decompositions:

11 + 8725361 = 8725372
53 + 8725319 = 8725372
233 + 8725139 = 8725372
239 + 8725133 = 8725372
269 + 8725103 = 8725372
281 + 8725091 = 8725372
389 + 8724983 = 8725372
443 + 8724929 = 8725372

Showing the first eight; more decompositions exist.
