Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642318, here are decompositions:

37 + 8642281 = 8642318
199 + 8642119 = 8642318
211 + 8642107 = 8642318
241 + 8642077 = 8642318
331 + 8641987 = 8642318
409 + 8641909 = 8642318
499 + 8641819 = 8642318
571 + 8641747 = 8642318

Showing the first eight; more decompositions exist.
