Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562016, here are decompositions:

7 + 31562009 = 31562016
23 + 31561993 = 31562016
43 + 31561973 = 31562016
47 + 31561969 = 31562016
89 + 31561927 = 31562016
97 + 31561919 = 31562016
113 + 31561903 = 31562016
193 + 31561823 = 31562016

Showing the first eight; more decompositions exist.
