Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671492, here are decompositions:

23 + 8671469 = 8671492
29 + 8671463 = 8671492
83 + 8671409 = 8671492
131 + 8671361 = 8671492
359 + 8671133 = 8671492
461 + 8671031 = 8671492
503 + 8670989 = 8671492
701 + 8670791 = 8671492

Showing the first eight; more decompositions exist.
