Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581342, here are decompositions:

19 + 581323 = 581342
31 + 581311 = 581342
79 + 581263 = 581342
103 + 581239 = 581342
193 + 581149 = 581342
199 + 581143 = 581342
241 + 581101 = 581342
271 + 581071 = 581342

Showing the first eight; more decompositions exist.
