Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687932, here are decompositions:

3 + 8687929 = 8687932
41 + 8687891 = 8687932
53 + 8687879 = 8687932
59 + 8687873 = 8687932
173 + 8687759 = 8687932
233 + 8687699 = 8687932
263 + 8687669 = 8687932
419 + 8687513 = 8687932

Showing the first eight; more decompositions exist.
