Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580734, here are decompositions:

23 + 31580711 = 31580734
41 + 31580693 = 31580734
47 + 31580687 = 31580734
113 + 31580621 = 31580734
233 + 31580501 = 31580734
257 + 31580477 = 31580734
281 + 31580453 = 31580734
461 + 31580273 = 31580734

Showing the first eight; more decompositions exist.
