Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670142, here are decompositions:

53 + 8670089 = 8670142
71 + 8670071 = 8670142
101 + 8670041 = 8670142
113 + 8670029 = 8670142
149 + 8669993 = 8670142
179 + 8669963 = 8670142
263 + 8669879 = 8670142
281 + 8669861 = 8670142

Showing the first eight; more decompositions exist.
