Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142100, here are decompositions:

3 + 142097 = 142100
43 + 142057 = 142100
61 + 142039 = 142100
109 + 141991 = 142100
139 + 141961 = 142100
163 + 141937 = 142100
193 + 141907 = 142100
229 + 141871 = 142100

Showing the first eight; more decompositions exist.
