Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527372, here are decompositions:

29 + 31527343 = 31527372
61 + 31527311 = 31527372
139 + 31527233 = 31527372
179 + 31527193 = 31527372
181 + 31527191 = 31527372
199 + 31527173 = 31527372
223 + 31527149 = 31527372
229 + 31527143 = 31527372

Showing the first eight; more decompositions exist.
