Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622402, here are decompositions:

11 + 8622391 = 8622402
23 + 8622379 = 8622402
29 + 8622373 = 8622402
43 + 8622359 = 8622402
59 + 8622343 = 8622402
71 + 8622331 = 8622402
79 + 8622323 = 8622402
101 + 8622301 = 8622402

Showing the first eight; more decompositions exist.
