Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562524, here are decompositions:

5 + 31562519 = 31562524
23 + 31562501 = 31562524
41 + 31562483 = 31562524
83 + 31562441 = 31562524
101 + 31562423 = 31562524
167 + 31562357 = 31562524
233 + 31562291 = 31562524
251 + 31562273 = 31562524

Showing the first eight; more decompositions exist.
