Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531772, here are decompositions:

41 + 531731 = 531772
71 + 531701 = 531772
83 + 531689 = 531772
149 + 531623 = 531772
191 + 531581 = 531772
251 + 531521 = 531772
389 + 531383 = 531772
419 + 531353 = 531772

Showing the first eight; more decompositions exist.
