Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608400, here are decompositions:

43 + 8608357 = 8608400
67 + 8608333 = 8608400
79 + 8608321 = 8608400
109 + 8608291 = 8608400
139 + 8608261 = 8608400
373 + 8608027 = 8608400
457 + 8607943 = 8608400
487 + 8607913 = 8608400

Showing the first eight; more decompositions exist.
