Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620532, here are decompositions:

11 + 31620521 = 31620532
59 + 31620473 = 31620532
89 + 31620443 = 31620532
101 + 31620431 = 31620532
173 + 31620359 = 31620532
233 + 31620299 = 31620532
263 + 31620269 = 31620532
269 + 31620263 = 31620532

Showing the first eight; more decompositions exist.
