Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562474, here are decompositions:

7 + 31562467 = 31562474
43 + 31562431 = 31562474
127 + 31562347 = 31562474
193 + 31562281 = 31562474
211 + 31562263 = 31562474
337 + 31562137 = 31562474
367 + 31562107 = 31562474
421 + 31562053 = 31562474

Showing the first eight; more decompositions exist.
