Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701142, here are decompositions:

19 + 8701123 = 8701142
61 + 8701081 = 8701142
103 + 8701039 = 8701142
211 + 8700931 = 8701142
271 + 8700871 = 8701142
349 + 8700793 = 8701142
421 + 8700721 = 8701142
433 + 8700709 = 8701142

Showing the first eight; more decompositions exist.
