Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488364, here are decompositions:

41 + 31488323 = 31488364
71 + 31488293 = 31488364
107 + 31488257 = 31488364
137 + 31488227 = 31488364
227 + 31488137 = 31488364
263 + 31488101 = 31488364
293 + 31488071 = 31488364
311 + 31488053 = 31488364

Showing the first eight; more decompositions exist.
