Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144002, here are decompositions:

3 + 143999 = 144002
31 + 143971 = 144002
181 + 143821 = 144002
211 + 143791 = 144002
223 + 143779 = 144002
283 + 143719 = 144002
349 + 143653 = 144002
373 + 143629 = 144002

Showing the first eight; more decompositions exist.
