Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700082, here are decompositions:

3 + 8700079 = 8700082
11 + 8700071 = 8700082
23 + 8700059 = 8700082
71 + 8700011 = 8700082
89 + 8699993 = 8700082
101 + 8699981 = 8700082
113 + 8699969 = 8700082
269 + 8699813 = 8700082

Showing the first eight; more decompositions exist.
