Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671392, here are decompositions:

11 + 8671381 = 8671392
29 + 8671363 = 8671392
31 + 8671361 = 8671392
53 + 8671339 = 8671392
61 + 8671331 = 8671392
71 + 8671321 = 8671392
101 + 8671291 = 8671392
173 + 8671219 = 8671392

Showing the first eight; more decompositions exist.
