Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671380, here are decompositions:

13 + 8671367 = 8671380
17 + 8671363 = 8671380
19 + 8671361 = 8671380
41 + 8671339 = 8671380
59 + 8671321 = 8671380
73 + 8671307 = 8671380
89 + 8671291 = 8671380
131 + 8671249 = 8671380

Showing the first eight; more decompositions exist.
