Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653142, here are decompositions:

31 + 8653111 = 8653142
61 + 8653081 = 8653142
79 + 8653063 = 8653142
163 + 8652979 = 8653142
229 + 8652913 = 8653142
349 + 8652793 = 8653142
439 + 8652703 = 8653142
541 + 8652601 = 8653142

Showing the first eight; more decompositions exist.
