Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031142, here are decompositions:

5 + 1031137 = 1031142
23 + 1031119 = 1031142
61 + 1031081 = 1031142
89 + 1031053 = 1031142
139 + 1031003 = 1031142
149 + 1030993 = 1031142
191 + 1030951 = 1031142
193 + 1030949 = 1031142

Showing the first eight; more decompositions exist.
