Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647342, here are decompositions:

89 + 8647253 = 8647342
113 + 8647229 = 8647342
149 + 8647193 = 8647342
251 + 8647091 = 8647342
281 + 8647061 = 8647342
311 + 8647031 = 8647342
443 + 8646899 = 8647342
491 + 8646851 = 8647342

Showing the first eight; more decompositions exist.
