Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581076, here are decompositions:

5 + 581071 = 581076
7 + 581069 = 581076
29 + 581047 = 581076
47 + 581029 = 581076
79 + 580997 = 581076
107 + 580969 = 581076
137 + 580939 = 581076
149 + 580927 = 581076

Showing the first eight; more decompositions exist.
