Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527300, here are decompositions:

23 + 31527277 = 31527300
47 + 31527253 = 31527300
53 + 31527247 = 31527300
67 + 31527233 = 31527300
89 + 31527211 = 31527300
107 + 31527193 = 31527300
109 + 31527191 = 31527300
127 + 31527173 = 31527300

Showing the first eight; more decompositions exist.
