Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725438, here are decompositions:

17 + 8725421 = 8725438
41 + 8725397 = 8725438
47 + 8725391 = 8725438
131 + 8725307 = 8725438
347 + 8725091 = 8725438
401 + 8725037 = 8725438
509 + 8724929 = 8725438
719 + 8724719 = 8725438

Showing the first eight; more decompositions exist.
