Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625432, here are decompositions:

73 + 8625359 = 8625432
83 + 8625349 = 8625432
89 + 8625343 = 8625432
131 + 8625301 = 8625432
199 + 8625233 = 8625432
229 + 8625203 = 8625432
241 + 8625191 = 8625432
311 + 8625121 = 8625432

Showing the first eight; more decompositions exist.
