Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562514, here are decompositions:

13 + 31562501 = 31562514
31 + 31562483 = 31562514
47 + 31562467 = 31562514
73 + 31562441 = 31562514
83 + 31562431 = 31562514
157 + 31562357 = 31562514
167 + 31562347 = 31562514
223 + 31562291 = 31562514

Showing the first eight; more decompositions exist.
