Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735986, here are decompositions:

53 + 8735933 = 8735986
89 + 8735897 = 8735986
107 + 8735879 = 8735986
137 + 8735849 = 8735986
173 + 8735813 = 8735986
197 + 8735789 = 8735986
353 + 8735633 = 8735986
449 + 8735537 = 8735986

Showing the first eight; more decompositions exist.
