Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446164, here are decompositions:

31 + 31446133 = 31446164
67 + 31446097 = 31446164
97 + 31446067 = 31446164
103 + 31446061 = 31446164
181 + 31445983 = 31446164
223 + 31445941 = 31446164
313 + 31445851 = 31446164
331 + 31445833 = 31446164

Showing the first eight; more decompositions exist.
