Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531976, here are decompositions:

113 + 531863 = 531976
149 + 531827 = 531976
353 + 531623 = 531976
479 + 531497 = 531976
593 + 531383 = 531976
617 + 531359 = 531976
677 + 531299 = 531976
773 + 531203 = 531976

Showing the first eight; more decompositions exist.
