Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657378, here are decompositions:

139 + 8657239 = 8657378
157 + 8657221 = 8657378
337 + 8657041 = 8657378
439 + 8656939 = 8657378
487 + 8656891 = 8657378
547 + 8656831 = 8657378
571 + 8656807 = 8657378
577 + 8656801 = 8657378

Showing the first eight; more decompositions exist.
