Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562444, here are decompositions:

3 + 31562441 = 31562444
13 + 31562431 = 31562444
97 + 31562347 = 31562444
163 + 31562281 = 31562444
181 + 31562263 = 31562444
307 + 31562137 = 31562444
337 + 31562107 = 31562444
421 + 31562023 = 31562444

Showing the first eight; more decompositions exist.
