Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562814, here are decompositions:

13 + 31562801 = 31562814
37 + 31562777 = 31562814
47 + 31562767 = 31562814
103 + 31562711 = 31562814
131 + 31562683 = 31562814
137 + 31562677 = 31562814
191 + 31562623 = 31562814
193 + 31562621 = 31562814

Showing the first eight; more decompositions exist.
