Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672342, here are decompositions:

79 + 8672263 = 8672342
103 + 8672239 = 8672342
139 + 8672203 = 8672342
181 + 8672161 = 8672342
241 + 8672101 = 8672342
631 + 8671711 = 8672342
673 + 8671669 = 8672342
709 + 8671633 = 8672342

Showing the first eight; more decompositions exist.
