Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642412, here are decompositions:

29 + 8642383 = 8642412
83 + 8642329 = 8642412
109 + 8642303 = 8642412
131 + 8642281 = 8642412
223 + 8642189 = 8642412
239 + 8642173 = 8642412
271 + 8642141 = 8642412
293 + 8642119 = 8642412

Showing the first eight; more decompositions exist.
