Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657162, here are decompositions:

109 + 8657053 = 8657162
223 + 8656939 = 8657162
229 + 8656933 = 8657162
271 + 8656891 = 8657162
313 + 8656849 = 8657162
331 + 8656831 = 8657162
433 + 8656729 = 8657162
601 + 8656561 = 8657162

Showing the first eight; more decompositions exist.
