Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642282, here are decompositions:

109 + 8642173 = 8642282
163 + 8642119 = 8642282
223 + 8642059 = 8642282
373 + 8641909 = 8642282
409 + 8641873 = 8642282
463 + 8641819 = 8642282
499 + 8641783 = 8642282
541 + 8641741 = 8642282

Showing the first eight; more decompositions exist.
