Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050142, here are decompositions:

3 + 1050139 = 1050142
59 + 1050083 = 1050142
89 + 1050053 = 1050142
101 + 1050041 = 1050142
131 + 1050011 = 1050142
179 + 1049963 = 1050142
251 + 1049891 = 1050142
281 + 1049861 = 1050142

Showing the first eight; more decompositions exist.
