Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488382, here are decompositions:

11 + 31488371 = 31488382
53 + 31488329 = 31488382
59 + 31488323 = 31488382
83 + 31488299 = 31488382
89 + 31488293 = 31488382
179 + 31488203 = 31488382
281 + 31488101 = 31488382
293 + 31488089 = 31488382

Showing the first eight; more decompositions exist.
