Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580962, here are decompositions:

3 + 31580959 = 31580962
5 + 31580957 = 31580962
71 + 31580891 = 31580962
173 + 31580789 = 31580962
251 + 31580711 = 31580962
269 + 31580693 = 31580962
293 + 31580669 = 31580962
431 + 31580531 = 31580962

Showing the first eight; more decompositions exist.
