Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581526, here are decompositions:

5 + 581521 = 581526
53 + 581473 = 581526
67 + 581459 = 581526
79 + 581447 = 581526
83 + 581443 = 581526
97 + 581429 = 581526
149 + 581377 = 581526
157 + 581369 = 581526

Showing the first eight; more decompositions exist.
