Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670862, here are decompositions:

71 + 8670791 = 8670862
89 + 8670773 = 8670862
149 + 8670713 = 8670862
251 + 8670611 = 8670862
311 + 8670551 = 8670862
353 + 8670509 = 8670862
359 + 8670503 = 8670862
491 + 8670371 = 8670862

Showing the first eight; more decompositions exist.
