Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571506, here are decompositions:

29 + 571477 = 571506
53 + 571453 = 571506
73 + 571433 = 571506
97 + 571409 = 571506
107 + 571399 = 571506
109 + 571397 = 571506
137 + 571369 = 571506
167 + 571339 = 571506

Showing the first eight; more decompositions exist.
