Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527294, here are decompositions:

17 + 31527277 = 31527294
41 + 31527253 = 31527294
47 + 31527247 = 31527294
61 + 31527233 = 31527294
83 + 31527211 = 31527294
101 + 31527193 = 31527294
103 + 31527191 = 31527294
137 + 31527157 = 31527294

Showing the first eight; more decompositions exist.
