Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580996, here are decompositions:

37 + 31580959 = 31580996
67 + 31580929 = 31580996
277 + 31580719 = 31580996
313 + 31580683 = 31580996
379 + 31580617 = 31580996
439 + 31580557 = 31580996
457 + 31580539 = 31580996
673 + 31580323 = 31580996

Showing the first eight; more decompositions exist.
