Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527270, here are decompositions:

17 + 31527253 = 31527270
23 + 31527247 = 31527270
37 + 31527233 = 31527270
59 + 31527211 = 31527270
79 + 31527191 = 31527270
97 + 31527173 = 31527270
113 + 31527157 = 31527270
127 + 31527143 = 31527270

Showing the first eight; more decompositions exist.
