Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488346, here are decompositions:

17 + 31488329 = 31488346
23 + 31488323 = 31488346
47 + 31488299 = 31488346
53 + 31488293 = 31488346
89 + 31488257 = 31488346
257 + 31488089 = 31488346
293 + 31488053 = 31488346
353 + 31487993 = 31488346

Showing the first eight; more decompositions exist.
