Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533050, here are decompositions:

37 + 31533013 = 31533050
79 + 31532971 = 31533050
127 + 31532923 = 31533050
151 + 31532899 = 31533050
313 + 31532737 = 31533050
397 + 31532653 = 31533050
457 + 31532593 = 31533050
463 + 31532587 = 31533050

Showing the first eight; more decompositions exist.
