Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143250, here are decompositions:

7 + 143243 = 143250
11 + 143239 = 143250
53 + 143197 = 143250
73 + 143177 = 143250
109 + 143141 = 143250
113 + 143137 = 143250
137 + 143113 = 143250
139 + 143111 = 143250

Showing the first eight; more decompositions exist.
