Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616402, here are decompositions:

5 + 8616397 = 8616402
23 + 8616379 = 8616402
29 + 8616373 = 8616402
31 + 8616371 = 8616402
79 + 8616323 = 8616402
83 + 8616319 = 8616402
103 + 8616299 = 8616402
131 + 8616271 = 8616402

Showing the first eight; more decompositions exist.
