Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446270, here are decompositions:

13 + 31446257 = 31446270
17 + 31446253 = 31446270
19 + 31446251 = 31446270
29 + 31446241 = 31446270
41 + 31446229 = 31446270
43 + 31446227 = 31446270
47 + 31446223 = 31446270
59 + 31446211 = 31446270

Showing the first eight; more decompositions exist.
