Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561734, here are decompositions:

5 + 31561729 = 31561734
11 + 31561723 = 31561734
23 + 31561711 = 31561734
37 + 31561697 = 31561734
41 + 31561693 = 31561734
73 + 31561661 = 31561734
103 + 31561631 = 31561734
137 + 31561597 = 31561734

Showing the first eight; more decompositions exist.
