Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661426, here are decompositions:

13 + 8661413 = 8661426
19 + 8661407 = 8661426
43 + 8661383 = 8661426
73 + 8661353 = 8661426
173 + 8661253 = 8661426
223 + 8661203 = 8661426
229 + 8661197 = 8661426
233 + 8661193 = 8661426

Showing the first eight; more decompositions exist.
