Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562948, here are decompositions:

31 + 31562917 = 31562948
37 + 31562911 = 31562948
181 + 31562767 = 31562948
211 + 31562737 = 31562948
271 + 31562677 = 31562948
331 + 31562617 = 31562948
337 + 31562611 = 31562948
397 + 31562551 = 31562948

Showing the first eight; more decompositions exist.
