Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642204, here are decompositions:

7 + 8642197 = 8642204
31 + 8642173 = 8642204
97 + 8642107 = 8642204
127 + 8642077 = 8642204
313 + 8641891 = 8642204
331 + 8641873 = 8642204
397 + 8641807 = 8642204
421 + 8641783 = 8642204

Showing the first eight; more decompositions exist.
