Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533404, here are decompositions:

61 + 31533343 = 31533404
271 + 31533133 = 31533404
277 + 31533127 = 31533404
307 + 31533097 = 31533404
313 + 31533091 = 31533404
433 + 31532971 = 31533404
523 + 31532881 = 31533404
541 + 31532863 = 31533404

Showing the first eight; more decompositions exist.
