Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562014, here are decompositions:

5 + 31562009 = 31562014
41 + 31561973 = 31562014
47 + 31561967 = 31562014
167 + 31561847 = 31562014
191 + 31561823 = 31562014
233 + 31561781 = 31562014
317 + 31561697 = 31562014
353 + 31561661 = 31562014

Showing the first eight; more decompositions exist.
