Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460734, here are decompositions:

5 + 31460729 = 31460734
17 + 31460717 = 31460734
197 + 31460537 = 31460734
251 + 31460483 = 31460734
293 + 31460441 = 31460734
443 + 31460291 = 31460734
467 + 31460267 = 31460734
797 + 31459937 = 31460734

Showing the first eight; more decompositions exist.
