Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671862, here are decompositions:

151 + 8671711 = 8671862
193 + 8671669 = 8671862
223 + 8671639 = 8671862
229 + 8671633 = 8671862
313 + 8671549 = 8671862
421 + 8671441 = 8671862
499 + 8671363 = 8671862
523 + 8671339 = 8671862

Showing the first eight; more decompositions exist.
