Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612970, here are decompositions:

11 + 8612959 = 8612970
13 + 8612957 = 8612970
29 + 8612941 = 8612970
43 + 8612927 = 8612970
97 + 8612873 = 8612970
109 + 8612861 = 8612970
131 + 8612839 = 8612970
139 + 8612831 = 8612970

Showing the first eight; more decompositions exist.
