Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562392, here are decompositions:

3 + 31562389 = 31562392
101 + 31562291 = 31562392
131 + 31562261 = 31562392
149 + 31562243 = 31562392
179 + 31562213 = 31562392
293 + 31562099 = 31562392
359 + 31562033 = 31562392
383 + 31562009 = 31562392

Showing the first eight; more decompositions exist.
