Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671838, here are decompositions:

127 + 8671711 = 8671838
199 + 8671639 = 8671838
337 + 8671501 = 8671838
367 + 8671471 = 8671838
397 + 8671441 = 8671838
457 + 8671381 = 8671838
499 + 8671339 = 8671838
547 + 8671291 = 8671838

Showing the first eight; more decompositions exist.
