Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533524, here are decompositions:

7 + 31533517 = 31533524
13 + 31533511 = 31533524
73 + 31533451 = 31533524
181 + 31533343 = 31533524
397 + 31533127 = 31533524
433 + 31533091 = 31533524
523 + 31533001 = 31533524
601 + 31532923 = 31533524

Showing the first eight; more decompositions exist.
