Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488544, here are decompositions:

47 + 31488497 = 31488544
137 + 31488407 = 31488544
173 + 31488371 = 31488544
251 + 31488293 = 31488544
317 + 31488227 = 31488544
383 + 31488161 = 31488544
443 + 31488101 = 31488544
491 + 31488053 = 31488544

Showing the first eight; more decompositions exist.
