Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672312, here are decompositions:

73 + 8672239 = 8672312
109 + 8672203 = 8672312
151 + 8672161 = 8672312
211 + 8672101 = 8672312
331 + 8671981 = 8672312
601 + 8671711 = 8672312
643 + 8671669 = 8672312
673 + 8671639 = 8672312

Showing the first eight; more decompositions exist.
