Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673642, here are decompositions:

31 + 8673611 = 8673642
41 + 8673601 = 8673642
71 + 8673571 = 8673642
73 + 8673569 = 8673642
179 + 8673463 = 8673642
223 + 8673419 = 8673642
269 + 8673373 = 8673642
281 + 8673361 = 8673642

Showing the first eight; more decompositions exist.
