Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735920, here are decompositions:

23 + 8735897 = 8735920
29 + 8735891 = 8735920
41 + 8735879 = 8735920
59 + 8735861 = 8735920
71 + 8735849 = 8735920
107 + 8735813 = 8735920
131 + 8735789 = 8735920
239 + 8735681 = 8735920

Showing the first eight; more decompositions exist.
