Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671372, here are decompositions:

5 + 8671367 = 8671372
11 + 8671361 = 8671372
41 + 8671331 = 8671372
179 + 8671193 = 8671372
239 + 8671133 = 8671372
383 + 8670989 = 8671372
431 + 8670941 = 8671372
503 + 8670869 = 8671372

Showing the first eight; more decompositions exist.
