Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725432, here are decompositions:

3 + 8725429 = 8725432
11 + 8725421 = 8725432
41 + 8725391 = 8725432
71 + 8725361 = 8725432
113 + 8725319 = 8725432
179 + 8725253 = 8725432
293 + 8725139 = 8725432
449 + 8724983 = 8725432

Showing the first eight; more decompositions exist.
