Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701920, here are decompositions:

13 + 8701907 = 8701920
37 + 8701883 = 8701920
43 + 8701877 = 8701920
47 + 8701873 = 8701920
67 + 8701853 = 8701920
107 + 8701813 = 8701920
109 + 8701811 = 8701920
131 + 8701789 = 8701920

Showing the first eight; more decompositions exist.
