Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642546, here are decompositions:

13 + 8642533 = 8642546
37 + 8642509 = 8642546
79 + 8642467 = 8642546
97 + 8642449 = 8642546
163 + 8642383 = 8642546
349 + 8642197 = 8642546
373 + 8642173 = 8642546
439 + 8642107 = 8642546

Showing the first eight; more decompositions exist.
