Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496416, here are decompositions:

47 + 31496369 = 31496416
197 + 31496219 = 31496416
293 + 31496123 = 31496416
317 + 31496099 = 31496416
359 + 31496057 = 31496416
389 + 31496027 = 31496416
467 + 31495949 = 31496416
557 + 31495859 = 31496416

Showing the first eight; more decompositions exist.
