Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142532, here are decompositions:

3 + 142529 = 142532
31 + 142501 = 142532
79 + 142453 = 142532
151 + 142381 = 142532
163 + 142369 = 142532
349 + 142183 = 142532
373 + 142159 = 142532
409 + 142123 = 142532

Showing the first eight; more decompositions exist.
