Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527260, here are decompositions:

7 + 31527253 = 31527260
13 + 31527247 = 31527260
67 + 31527193 = 31527260
103 + 31527157 = 31527260
109 + 31527151 = 31527260
151 + 31527109 = 31527260
307 + 31526953 = 31527260
367 + 31526893 = 31527260

Showing the first eight; more decompositions exist.
