Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608142, here are decompositions:

61 + 8608081 = 8608142
199 + 8607943 = 8608142
229 + 8607913 = 8608142
241 + 8607901 = 8608142
271 + 8607871 = 8608142
373 + 8607769 = 8608142
409 + 8607733 = 8608142
541 + 8607601 = 8608142

Showing the first eight; more decompositions exist.
