Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562200, here are decompositions:

83 + 31562117 = 31562200
101 + 31562099 = 31562200
107 + 31562093 = 31562200
167 + 31562033 = 31562200
191 + 31562009 = 31562200
227 + 31561973 = 31562200
233 + 31561967 = 31562200
281 + 31561919 = 31562200

Showing the first eight; more decompositions exist.
