Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531626, here are decompositions:

3 + 531623 = 531626
13 + 531613 = 531626
37 + 531589 = 531626
79 + 531547 = 531626
283 + 531343 = 531626
373 + 531253 = 531626
397 + 531229 = 531626
457 + 531169 = 531626

Showing the first eight; more decompositions exist.
