Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580596, here are decompositions:

227 + 31580369 = 31580596
269 + 31580327 = 31580596
317 + 31580279 = 31580596
389 + 31580207 = 31580596
419 + 31580177 = 31580596
503 + 31580093 = 31580596
587 + 31580009 = 31580596
683 + 31579913 = 31580596

Showing the first eight; more decompositions exist.
