Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446326, here are decompositions:

3 + 31446323 = 31446326
73 + 31446253 = 31446326
97 + 31446229 = 31446326
103 + 31446223 = 31446326
193 + 31446133 = 31446326
229 + 31446097 = 31446326
349 + 31445977 = 31446326
367 + 31445959 = 31446326

Showing the first eight; more decompositions exist.
