Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83542, here are decompositions:

5 + 83537 = 83542
71 + 83471 = 83542
83 + 83459 = 83542
269 + 83273 = 83542
311 + 83231 = 83542
449 + 83093 = 83542
479 + 83063 = 83542
653 + 82889 = 83542

Showing the first eight; more decompositions exist.
