Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580598, here are decompositions:

41 + 31580557 = 31580598
59 + 31580539 = 31580598
67 + 31580531 = 31580598
97 + 31580501 = 31580598
229 + 31580369 = 31580598
251 + 31580347 = 31580598
271 + 31580327 = 31580598
277 + 31580321 = 31580598

Showing the first eight; more decompositions exist.
