Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642906, here are decompositions:

3 + 8642903 = 8642906
43 + 8642863 = 8642906
67 + 8642839 = 8642906
373 + 8642533 = 8642906
397 + 8642509 = 8642906
439 + 8642467 = 8642906
457 + 8642449 = 8642906
523 + 8642383 = 8642906

Showing the first eight; more decompositions exist.
