Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581070, here are decompositions:

23 + 581047 = 581070
29 + 581041 = 581070
41 + 581029 = 581070
73 + 580997 = 581070
89 + 580981 = 581070
101 + 580969 = 581070
131 + 580939 = 581070
151 + 580919 = 581070

Showing the first eight; more decompositions exist.
