Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562236, here are decompositions:

5 + 31562231 = 31562236
23 + 31562213 = 31562236
137 + 31562099 = 31562236
179 + 31562057 = 31562236
227 + 31562009 = 31562236
263 + 31561973 = 31562236
269 + 31561967 = 31562236
317 + 31561919 = 31562236

Showing the first eight; more decompositions exist.
