Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562674, here are decompositions:

47 + 31562627 = 31562674
53 + 31562621 = 31562674
71 + 31562603 = 31562674
107 + 31562567 = 31562674
131 + 31562543 = 31562674
173 + 31562501 = 31562674
191 + 31562483 = 31562674
233 + 31562441 = 31562674

Showing the first eight; more decompositions exist.
