Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642930, here are decompositions:

3 + 8642927 = 8642930
19 + 8642911 = 8642930
67 + 8642863 = 8642930
73 + 8642857 = 8642930
157 + 8642773 = 8642930
349 + 8642581 = 8642930
397 + 8642533 = 8642930
421 + 8642509 = 8642930

Showing the first eight; more decompositions exist.
