Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533464, here are decompositions:

3 + 31533461 = 31533464
13 + 31533451 = 31533464
331 + 31533133 = 31533464
337 + 31533127 = 31533464
367 + 31533097 = 31533464
373 + 31533091 = 31533464
463 + 31533001 = 31533464
541 + 31532923 = 31533464

Showing the first eight; more decompositions exist.
