Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446328, here are decompositions:

5 + 31446323 = 31446328
71 + 31446257 = 31446328
101 + 31446227 = 31446328
197 + 31446131 = 31446328
227 + 31446101 = 31446328
317 + 31446011 = 31446328
467 + 31445861 = 31446328
479 + 31445849 = 31446328

Showing the first eight; more decompositions exist.
