Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012142, here are decompositions:

163 + 1011979 = 1012142
181 + 1011961 = 1012142
199 + 1011943 = 1012142
379 + 1011763 = 1012142
409 + 1011733 = 1012142
541 + 1011601 = 1012142
751 + 1011391 = 1012142
811 + 1011331 = 1012142

Showing the first eight; more decompositions exist.
