Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581734, here are decompositions:

3 + 581731 = 581734
5 + 581729 = 581734
47 + 581687 = 581734
71 + 581663 = 581734
137 + 581597 = 581734
383 + 581351 = 581734
401 + 581333 = 581734
431 + 581303 = 581734

Showing the first eight; more decompositions exist.
