Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562206, here are decompositions:

89 + 31562117 = 31562206
107 + 31562099 = 31562206
113 + 31562093 = 31562206
149 + 31562057 = 31562206
173 + 31562033 = 31562206
197 + 31562009 = 31562206
233 + 31561973 = 31562206
239 + 31561967 = 31562206

Showing the first eight; more decompositions exist.
