Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531964, here are decompositions:

53 + 531911 = 531964
101 + 531863 = 531964
107 + 531857 = 531964
131 + 531833 = 531964
137 + 531827 = 531964
233 + 531731 = 531964
263 + 531701 = 531964
353 + 531611 = 531964

Showing the first eight; more decompositions exist.
