Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620552, here are decompositions:

31 + 31620521 = 31620552
53 + 31620499 = 31620552
71 + 31620481 = 31620552
79 + 31620473 = 31620552
109 + 31620443 = 31620552
193 + 31620359 = 31620552
251 + 31620301 = 31620552
283 + 31620269 = 31620552

Showing the first eight; more decompositions exist.
