Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142038, here are decompositions:

7 + 142031 = 142038
19 + 142019 = 142038
31 + 142007 = 142038
47 + 141991 = 142038
67 + 141971 = 142038
79 + 141959 = 142038
97 + 141941 = 142038
101 + 141937 = 142038

Showing the first eight; more decompositions exist.
