Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562062, here are decompositions:

5 + 31562057 = 31562062
29 + 31562033 = 31562062
53 + 31562009 = 31562062
89 + 31561973 = 31562062
239 + 31561823 = 31562062
251 + 31561811 = 31562062
281 + 31561781 = 31562062
401 + 31561661 = 31562062

Showing the first eight; more decompositions exist.
