Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580296, here are decompositions:

3 + 31580293 = 31580296
17 + 31580279 = 31580296
23 + 31580273 = 31580296
29 + 31580267 = 31580296
89 + 31580207 = 31580296
113 + 31580183 = 31580296
233 + 31580063 = 31580296
239 + 31580057 = 31580296

Showing the first eight; more decompositions exist.
