Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671402, here are decompositions:

41 + 8671361 = 8671402
71 + 8671331 = 8671402
251 + 8671151 = 8671402
269 + 8671133 = 8671402
461 + 8670941 = 8671402
659 + 8670743 = 8671402
911 + 8670491 = 8671402
1031 + 8670371 = 8671402

Showing the first eight; more decompositions exist.
