Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531902, here are decompositions:

31 + 531871 = 531902
61 + 531841 = 531902
79 + 531823 = 531902
103 + 531799 = 531902
109 + 531793 = 531902
229 + 531673 = 531902
271 + 531631 = 531902
313 + 531589 = 531902

Showing the first eight; more decompositions exist.
