Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591276, here are decompositions:

89 + 31591187 = 31591276
239 + 31591037 = 31591276
263 + 31591013 = 31591276
317 + 31590959 = 31591276
347 + 31590929 = 31591276
359 + 31590917 = 31591276
383 + 31590893 = 31591276
389 + 31590887 = 31591276

Showing the first eight; more decompositions exist.
