Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562224, here are decompositions:

11 + 31562213 = 31562224
107 + 31562117 = 31562224
131 + 31562093 = 31562224
167 + 31562057 = 31562224
191 + 31562033 = 31562224
251 + 31561973 = 31562224
257 + 31561967 = 31562224
401 + 31561823 = 31562224

Showing the first eight; more decompositions exist.
