Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562914, here are decompositions:

3 + 31562911 = 31562914
113 + 31562801 = 31562914
137 + 31562777 = 31562914
293 + 31562621 = 31562914
311 + 31562603 = 31562914
347 + 31562567 = 31562914
431 + 31562483 = 31562914
491 + 31562423 = 31562914

Showing the first eight; more decompositions exist.
