Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642162, here are decompositions:

3 + 8642159 = 8642162
43 + 8642119 = 8642162
103 + 8642059 = 8642162
271 + 8641891 = 8642162
379 + 8641783 = 8642162
421 + 8641741 = 8642162
541 + 8641621 = 8642162
619 + 8641543 = 8642162

Showing the first eight; more decompositions exist.
