Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671844, here are decompositions:

7 + 8671837 = 8671844
211 + 8671633 = 8671844
271 + 8671573 = 8671844
373 + 8671471 = 8671844
397 + 8671447 = 8671844
463 + 8671381 = 8671844
523 + 8671321 = 8671844
613 + 8671231 = 8671844

Showing the first eight; more decompositions exist.
