Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562844, here are decompositions:

17 + 31562827 = 31562844
43 + 31562801 = 31562844
67 + 31562777 = 31562844
107 + 31562737 = 31562844
167 + 31562677 = 31562844
223 + 31562621 = 31562844
227 + 31562617 = 31562844
233 + 31562611 = 31562844

Showing the first eight; more decompositions exist.
