Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527306, here are decompositions:

29 + 31527277 = 31527306
53 + 31527253 = 31527306
59 + 31527247 = 31527306
73 + 31527233 = 31527306
113 + 31527193 = 31527306
149 + 31527157 = 31527306
157 + 31527149 = 31527306
163 + 31527143 = 31527306

Showing the first eight; more decompositions exist.
