Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642422, here are decompositions:

233 + 8642189 = 8642422
263 + 8642159 = 8642422
281 + 8642141 = 8642422
311 + 8642111 = 8642422
359 + 8642063 = 8642422
389 + 8642033 = 8642422
419 + 8642003 = 8642422
431 + 8641991 = 8642422

Showing the first eight; more decompositions exist.
