Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8597942, here are decompositions:

79 + 8597863 = 8597942
103 + 8597839 = 8597942
313 + 8597629 = 8597942
421 + 8597521 = 8597942
571 + 8597371 = 8597942
601 + 8597341 = 8597942
643 + 8597299 = 8597942
739 + 8597203 = 8597942

Showing the first eight; more decompositions exist.
