Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581482, here are decompositions:

23 + 581459 = 581482
53 + 581429 = 581482
71 + 581411 = 581482
89 + 581393 = 581482
113 + 581369 = 581482
131 + 581351 = 581482
149 + 581333 = 581482
179 + 581303 = 581482

Showing the first eight; more decompositions exist.
