Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527330, here are decompositions:

7 + 31527323 = 31527330
13 + 31527317 = 31527330
19 + 31527311 = 31527330
53 + 31527277 = 31527330
83 + 31527247 = 31527330
97 + 31527233 = 31527330
137 + 31527193 = 31527330
139 + 31527191 = 31527330

Showing the first eight; more decompositions exist.
