Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562488, here are decompositions:

5 + 31562483 = 31562488
47 + 31562441 = 31562488
59 + 31562429 = 31562488
131 + 31562357 = 31562488
197 + 31562291 = 31562488
227 + 31562261 = 31562488
257 + 31562231 = 31562488
389 + 31562099 = 31562488

Showing the first eight; more decompositions exist.
