Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671982, here are decompositions:

3 + 8671979 = 8671982
271 + 8671711 = 8671982
313 + 8671669 = 8671982
349 + 8671633 = 8671982
409 + 8671573 = 8671982
433 + 8671549 = 8671982
463 + 8671519 = 8671982
541 + 8671441 = 8671982

Showing the first eight; more decompositions exist.
