Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488348, here are decompositions:

19 + 31488329 = 31488348
137 + 31488211 = 31488348
211 + 31488137 = 31488348
239 + 31488109 = 31488348
257 + 31488091 = 31488348
277 + 31488071 = 31488348
317 + 31488031 = 31488348
431 + 31487917 = 31488348

Showing the first eight; more decompositions exist.
