Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671558, here are decompositions:

41 + 8671517 = 8671558
47 + 8671511 = 8671558
59 + 8671499 = 8671558
89 + 8671469 = 8671558
101 + 8671457 = 8671558
131 + 8671427 = 8671558
149 + 8671409 = 8671558
191 + 8671367 = 8671558

Showing the first eight; more decompositions exist.
