Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702070, here are decompositions:

7 + 8702063 = 8702070
19 + 8702051 = 8702070
61 + 8702009 = 8702070
71 + 8701999 = 8702070
73 + 8701997 = 8702070
79 + 8701991 = 8702070
109 + 8701961 = 8702070
137 + 8701933 = 8702070

Showing the first eight; more decompositions exist.
