Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533052, here are decompositions:

53 + 31532999 = 31533052
71 + 31532981 = 31533052
113 + 31532939 = 31533052
179 + 31532873 = 31533052
359 + 31532693 = 31533052
479 + 31532573 = 31533052
563 + 31532489 = 31533052
773 + 31532279 = 31533052

Showing the first eight; more decompositions exist.
