Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670042, here are decompositions:

5 + 8670037 = 8670042
11 + 8670031 = 8670042
13 + 8670029 = 8670042
53 + 8669989 = 8670042
61 + 8669981 = 8670042
79 + 8669963 = 8670042
103 + 8669939 = 8670042
113 + 8669929 = 8670042

Showing the first eight; more decompositions exist.
