Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642232, here are decompositions:

43 + 8642189 = 8642232
59 + 8642173 = 8642232
73 + 8642159 = 8642232
113 + 8642119 = 8642232
173 + 8642059 = 8642232
199 + 8642033 = 8642232
229 + 8642003 = 8642232
241 + 8641991 = 8642232

Showing the first eight; more decompositions exist.
