Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562486, here are decompositions:

3 + 31562483 = 31562486
19 + 31562467 = 31562486
37 + 31562449 = 31562486
97 + 31562389 = 31562486
139 + 31562347 = 31562486
157 + 31562329 = 31562486
223 + 31562263 = 31562486
229 + 31562257 = 31562486

Showing the first eight; more decompositions exist.
