Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660402, here are decompositions:

19 + 8660383 = 8660402
139 + 8660263 = 8660402
181 + 8660221 = 8660402
199 + 8660203 = 8660402
241 + 8660161 = 8660402
349 + 8660053 = 8660402
463 + 8659939 = 8660402
661 + 8659741 = 8660402

Showing the first eight; more decompositions exist.
