Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619552, here are decompositions:

31 + 31619521 = 31619552
43 + 31619509 = 31619552
163 + 31619389 = 31619552
193 + 31619359 = 31619552
241 + 31619311 = 31619552
271 + 31619281 = 31619552
373 + 31619179 = 31619552
409 + 31619143 = 31619552

Showing the first eight; more decompositions exist.
