Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662870, here are decompositions:

3 + 8662867 = 8662870
11 + 8662859 = 8662870
17 + 8662853 = 8662870
59 + 8662811 = 8662870
71 + 8662799 = 8662870
101 + 8662769 = 8662870
317 + 8662553 = 8662870
353 + 8662517 = 8662870

Showing the first eight; more decompositions exist.
