Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725986, here are decompositions:

7 + 8725979 = 8725986
23 + 8725963 = 8725986
37 + 8725949 = 8725986
109 + 8725877 = 8725986
163 + 8725823 = 8725986
173 + 8725813 = 8725986
229 + 8725757 = 8725986
317 + 8725669 = 8725986

Showing the first eight; more decompositions exist.
