Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527276, here are decompositions:

23 + 31527253 = 31527276
29 + 31527247 = 31527276
43 + 31527233 = 31527276
83 + 31527193 = 31527276
103 + 31527173 = 31527276
127 + 31527149 = 31527276
167 + 31527109 = 31527276
199 + 31527077 = 31527276

Showing the first eight; more decompositions exist.
