Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735142, here are decompositions:

5 + 8735137 = 8735142
29 + 8735113 = 8735142
103 + 8735039 = 8735142
113 + 8735029 = 8735142
131 + 8735011 = 8735142
149 + 8734993 = 8735142
223 + 8734919 = 8735142
373 + 8734769 = 8735142

Showing the first eight; more decompositions exist.
