Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591360, here are decompositions:

11 + 31591349 = 31591360
23 + 31591337 = 31591360
29 + 31591331 = 31591360
173 + 31591187 = 31591360
293 + 31591067 = 31591360
347 + 31591013 = 31591360
401 + 31590959 = 31591360
419 + 31590941 = 31591360

Showing the first eight; more decompositions exist.
