Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142018, here are decompositions:

11 + 142007 = 142018
47 + 141971 = 142018
59 + 141959 = 142018
101 + 141917 = 142018
167 + 141851 = 142018
251 + 141767 = 142018
257 + 141761 = 142018
311 + 141707 = 142018

Showing the first eight; more decompositions exist.
