Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533446, here are decompositions:

37 + 31533409 = 31533446
67 + 31533379 = 31533446
103 + 31533343 = 31533446
313 + 31533133 = 31533446
349 + 31533097 = 31533446
433 + 31533013 = 31533446
487 + 31532959 = 31533446
523 + 31532923 = 31533446

Showing the first eight; more decompositions exist.
