Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725378, here are decompositions:

17 + 8725361 = 8725378
59 + 8725319 = 8725378
71 + 8725307 = 8725378
239 + 8725139 = 8725378
449 + 8724929 = 8725378
659 + 8724719 = 8725378
881 + 8724497 = 8725378
911 + 8724467 = 8725378

Showing the first eight; more decompositions exist.
