Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598482, here are decompositions:

23 + 31598459 = 31598482
59 + 31598423 = 31598482
101 + 31598381 = 31598482
269 + 31598213 = 31598482
281 + 31598201 = 31598482
449 + 31598033 = 31598482
521 + 31597961 = 31598482
569 + 31597913 = 31598482

Showing the first eight; more decompositions exist.
