Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670874, here are decompositions:

5 + 8670869 = 8670874
11 + 8670863 = 8670874
83 + 8670791 = 8670874
101 + 8670773 = 8670874
131 + 8670743 = 8670874
263 + 8670611 = 8670874
383 + 8670491 = 8670874
467 + 8670407 = 8670874

Showing the first eight; more decompositions exist.
