Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562532, here are decompositions:

13 + 31562519 = 31562532
31 + 31562501 = 31562532
83 + 31562449 = 31562532
101 + 31562431 = 31562532
103 + 31562429 = 31562532
109 + 31562423 = 31562532
233 + 31562299 = 31562532
241 + 31562291 = 31562532

Showing the first eight; more decompositions exist.
