Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581498, here are decompositions:

7 + 581491 = 581498
157 + 581341 = 581498
271 + 581227 = 581498
349 + 581149 = 581498
397 + 581101 = 581498
409 + 581089 = 581498
457 + 581041 = 581498
571 + 580927 = 581498

Showing the first eight; more decompositions exist.
