Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671438, here are decompositions:

11 + 8671427 = 8671438
29 + 8671409 = 8671438
71 + 8671367 = 8671438
107 + 8671331 = 8671438
131 + 8671307 = 8671438
311 + 8671127 = 8671438
431 + 8671007 = 8671438
449 + 8670989 = 8671438

Showing the first eight; more decompositions exist.
