Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642312, here are decompositions:

31 + 8642281 = 8642312
139 + 8642173 = 8642312
193 + 8642119 = 8642312
421 + 8641891 = 8642312
439 + 8641873 = 8642312
571 + 8641741 = 8642312
643 + 8641669 = 8642312
661 + 8641651 = 8642312

Showing the first eight; more decompositions exist.
