Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642098, here are decompositions:

41 + 8642057 = 8642098
71 + 8642027 = 8642098
107 + 8641991 = 8642098
149 + 8641949 = 8642098
281 + 8641817 = 8642098
317 + 8641781 = 8642098
389 + 8641709 = 8642098
401 + 8641697 = 8642098

Showing the first eight; more decompositions exist.
