Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657342, here are decompositions:

19 + 8657323 = 8657342
103 + 8657239 = 8657342
181 + 8657161 = 8657342
409 + 8656933 = 8657342
439 + 8656903 = 8657342
541 + 8656801 = 8657342
613 + 8656729 = 8657342
739 + 8656603 = 8657342

Showing the first eight; more decompositions exist.
