Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690142, here are decompositions:

23 + 8690119 = 8690142
53 + 8690089 = 8690142
73 + 8690069 = 8690142
79 + 8690063 = 8690142
101 + 8690041 = 8690142
163 + 8689979 = 8690142
173 + 8689969 = 8690142
193 + 8689949 = 8690142

Showing the first eight; more decompositions exist.
