Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581260, here are decompositions:

23 + 581237 = 581260
59 + 581201 = 581260
83 + 581177 = 581260
89 + 581171 = 581260
191 + 581069 = 581260
263 + 580997 = 581260
347 + 580913 = 581260
359 + 580901 = 581260

Showing the first eight; more decompositions exist.
