Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669162, here are decompositions:

3 + 8669159 = 8669162
79 + 8669083 = 8669162
211 + 8668951 = 8669162
331 + 8668831 = 8669162
349 + 8668813 = 8669162
379 + 8668783 = 8669162
421 + 8668741 = 8669162
613 + 8668549 = 8669162

Showing the first eight; more decompositions exist.
