Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562922, here are decompositions:

5 + 31562917 = 31562922
11 + 31562911 = 31562922
73 + 31562849 = 31562922
211 + 31562711 = 31562922
239 + 31562683 = 31562922
311 + 31562611 = 31562922
379 + 31562543 = 31562922
421 + 31562501 = 31562922

Showing the first eight; more decompositions exist.
