Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142210, here are decompositions:

17 + 142193 = 142210
41 + 142169 = 142210
53 + 142157 = 142210
59 + 142151 = 142210
113 + 142097 = 142210
149 + 142061 = 142210
179 + 142031 = 142210
191 + 142019 = 142210

Showing the first eight; more decompositions exist.
