Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712432, here are decompositions:

11 + 8712421 = 8712432
59 + 8712373 = 8712432
61 + 8712371 = 8712432
83 + 8712349 = 8712432
109 + 8712323 = 8712432
139 + 8712293 = 8712432
151 + 8712281 = 8712432
163 + 8712269 = 8712432

Showing the first eight; more decompositions exist.
