Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659400, here are decompositions:

7 + 8659393 = 8659400
19 + 8659381 = 8659400
37 + 8659363 = 8659400
157 + 8659243 = 8659400
181 + 8659219 = 8659400
193 + 8659207 = 8659400
349 + 8659051 = 8659400
439 + 8658961 = 8659400

Showing the first eight; more decompositions exist.
