Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719672, here are decompositions:

11 + 8719661 = 8719672
131 + 8719541 = 8719672
251 + 8719421 = 8719672
281 + 8719391 = 8719672
293 + 8719379 = 8719672
383 + 8719289 = 8719672
419 + 8719253 = 8719672
449 + 8719223 = 8719672

Showing the first eight; more decompositions exist.
