Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446276, here are decompositions:

19 + 31446257 = 31446276
23 + 31446253 = 31446276
47 + 31446229 = 31446276
53 + 31446223 = 31446276
109 + 31446167 = 31446276
179 + 31446097 = 31446276
223 + 31446053 = 31446276
293 + 31445983 = 31446276

Showing the first eight; more decompositions exist.
