Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712042, here are decompositions:

13 + 8712029 = 8712042
23 + 8712019 = 8712042
71 + 8711971 = 8712042
89 + 8711953 = 8712042
109 + 8711933 = 8712042
173 + 8711869 = 8712042
179 + 8711863 = 8712042
191 + 8711851 = 8712042

Showing the first eight; more decompositions exist.
