Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562492, here are decompositions:

43 + 31562449 = 31562492
61 + 31562431 = 31562492
103 + 31562389 = 31562492
163 + 31562329 = 31562492
193 + 31562299 = 31562492
211 + 31562281 = 31562492
229 + 31562263 = 31562492
373 + 31562119 = 31562492

Showing the first eight; more decompositions exist.
