Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581332, here are decompositions:

29 + 581303 = 581332
71 + 581261 = 581332
131 + 581201 = 581332
149 + 581183 = 581332
233 + 581099 = 581332
263 + 581069 = 581332
419 + 580913 = 581332
431 + 580901 = 581332

Showing the first eight; more decompositions exist.
