Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580932, here are decompositions:

3 + 31580929 = 31580932
41 + 31580891 = 31580932
191 + 31580741 = 31580932
239 + 31580693 = 31580932
263 + 31580669 = 31580932
311 + 31580621 = 31580932
401 + 31580531 = 31580932
431 + 31580501 = 31580932

Showing the first eight; more decompositions exist.
