Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670844, here are decompositions:

53 + 8670791 = 8670844
71 + 8670773 = 8670844
101 + 8670743 = 8670844
131 + 8670713 = 8670844
191 + 8670653 = 8670844
233 + 8670611 = 8670844
293 + 8670551 = 8670844
311 + 8670533 = 8670844

Showing the first eight; more decompositions exist.
