Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649402, here are decompositions:

11 + 8649391 = 8649402
19 + 8649383 = 8649402
31 + 8649371 = 8649402
53 + 8649349 = 8649402
59 + 8649343 = 8649402
71 + 8649331 = 8649402
79 + 8649323 = 8649402
103 + 8649299 = 8649402

Showing the first eight; more decompositions exist.
