Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488592, here are decompositions:

29 + 31488563 = 31488592
263 + 31488329 = 31488592
269 + 31488323 = 31488592
293 + 31488299 = 31488592
389 + 31488203 = 31488592
431 + 31488161 = 31488592
491 + 31488101 = 31488592
503 + 31488089 = 31488592

Showing the first eight; more decompositions exist.
