Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661724, here are decompositions:

17 + 8661707 = 8661724
41 + 8661683 = 8661724
83 + 8661641 = 8661724
101 + 8661623 = 8661724
167 + 8661557 = 8661724
233 + 8661491 = 8661724
263 + 8661461 = 8661724
311 + 8661413 = 8661724

Showing the first eight; more decompositions exist.
