Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527226, here are decompositions:

53 + 31527173 = 31527226
83 + 31527143 = 31527226
149 + 31527077 = 31527226
179 + 31527047 = 31527226
347 + 31526879 = 31527226
449 + 31526777 = 31527226
503 + 31526723 = 31527226
557 + 31526669 = 31527226

Showing the first eight; more decompositions exist.
