Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671898, here are decompositions:

61 + 8671837 = 8671898
229 + 8671669 = 8671898
349 + 8671549 = 8671898
379 + 8671519 = 8671898
397 + 8671501 = 8671898
457 + 8671441 = 8671898
577 + 8671321 = 8671898
607 + 8671291 = 8671898

Showing the first eight; more decompositions exist.
