Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661574, here are decompositions:

3 + 8661571 = 8661574
17 + 8661557 = 8661574
83 + 8661491 = 8661574
113 + 8661461 = 8661574
137 + 8661437 = 8661574
167 + 8661407 = 8661574
191 + 8661383 = 8661574
263 + 8661311 = 8661574

Showing the first eight; more decompositions exist.
