Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533532, here are decompositions:

71 + 31533461 = 31533532
83 + 31533449 = 31533532
101 + 31533431 = 31533532
263 + 31533269 = 31533532
383 + 31533149 = 31533532
389 + 31533143 = 31533532
431 + 31533101 = 31533532
593 + 31532939 = 31533532

Showing the first eight; more decompositions exist.
