Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661412, here are decompositions:

5 + 8661407 = 8661412
29 + 8661383 = 8661412
59 + 8661353 = 8661412
101 + 8661311 = 8661412
131 + 8661281 = 8661412
173 + 8661239 = 8661412
239 + 8661173 = 8661412
251 + 8661161 = 8661412

Showing the first eight; more decompositions exist.
