Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562544, here are decompositions:

43 + 31562501 = 31562544
61 + 31562483 = 31562544
103 + 31562441 = 31562544
113 + 31562431 = 31562544
197 + 31562347 = 31562544
263 + 31562281 = 31562544
271 + 31562273 = 31562544
281 + 31562263 = 31562544

Showing the first eight; more decompositions exist.
