Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642722, here are decompositions:

71 + 8642651 = 8642722
89 + 8642633 = 8642722
131 + 8642591 = 8642722
233 + 8642489 = 8642722
269 + 8642453 = 8642722
293 + 8642429 = 8642722
419 + 8642303 = 8642722
563 + 8642159 = 8642722

Showing the first eight; more decompositions exist.
