Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657372, here are decompositions:

151 + 8657221 = 8657372
211 + 8657161 = 8657372
331 + 8657041 = 8657372
433 + 8656939 = 8657372
439 + 8656933 = 8657372
523 + 8656849 = 8657372
541 + 8656831 = 8657372
571 + 8656801 = 8657372

Showing the first eight; more decompositions exist.
