Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620632, here are decompositions:

31 + 31620601 = 31620632
61 + 31620571 = 31620632
151 + 31620481 = 31620632
223 + 31620409 = 31620632
331 + 31620301 = 31620632
409 + 31620223 = 31620632
523 + 31620109 = 31620632
613 + 31620019 = 31620632

Showing the first eight; more decompositions exist.
