Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562076, here are decompositions:

19 + 31562057 = 31562076
23 + 31562053 = 31562076
43 + 31562033 = 31562076
53 + 31562023 = 31562076
59 + 31562017 = 31562076
67 + 31562009 = 31562076
83 + 31561993 = 31562076
103 + 31561973 = 31562076

Showing the first eight; more decompositions exist.
