Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671790, here are decompositions:

79 + 8671711 = 8671790
151 + 8671639 = 8671790
157 + 8671633 = 8671790
241 + 8671549 = 8671790
271 + 8671519 = 8671790
349 + 8671441 = 8671790
397 + 8671393 = 8671790
409 + 8671381 = 8671790

Showing the first eight; more decompositions exist.
