Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446304, here are decompositions:

47 + 31446257 = 31446304
53 + 31446251 = 31446304
137 + 31446167 = 31446304
173 + 31446131 = 31446304
251 + 31446053 = 31446304
293 + 31446011 = 31446304
347 + 31445957 = 31446304
443 + 31445861 = 31446304

Showing the first eight; more decompositions exist.
