Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533542, here are decompositions:

31 + 31533511 = 31533542
43 + 31533499 = 31533542
163 + 31533379 = 31533542
199 + 31533343 = 31533542
283 + 31533259 = 31533542
409 + 31533133 = 31533542
541 + 31533001 = 31533542
571 + 31532971 = 31533542

Showing the first eight; more decompositions exist.
