Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701938, here are decompositions:

5 + 8701933 = 8701938
17 + 8701921 = 8701938
31 + 8701907 = 8701938
61 + 8701877 = 8701938
67 + 8701871 = 8701938
127 + 8701811 = 8701938
149 + 8701789 = 8701938
181 + 8701757 = 8701938

Showing the first eight; more decompositions exist.
