Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561714, here are decompositions:

3 + 31561711 = 31561714
17 + 31561697 = 31561714
53 + 31561661 = 31561714
71 + 31561643 = 31561714
83 + 31561631 = 31561714
137 + 31561577 = 31561714
167 + 31561547 = 31561714
251 + 31561463 = 31561714

Showing the first eight; more decompositions exist.
