Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671972, here are decompositions:

5 + 8671967 = 8671972
53 + 8671919 = 8671972
233 + 8671739 = 8671972
251 + 8671721 = 8671972
263 + 8671709 = 8671972
383 + 8671589 = 8671972
389 + 8671583 = 8671972
461 + 8671511 = 8671972

Showing the first eight; more decompositions exist.
