Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726564, here are decompositions:

31 + 8726533 = 8726564
37 + 8726527 = 8726564
43 + 8726521 = 8726564
97 + 8726467 = 8726564
103 + 8726461 = 8726564
163 + 8726401 = 8726564
181 + 8726383 = 8726564
241 + 8726323 = 8726564

Showing the first eight; more decompositions exist.
