Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531764, here are decompositions:

97 + 531667 = 531764
127 + 531637 = 531764
151 + 531613 = 531764
193 + 531571 = 531764
283 + 531481 = 531764
307 + 531457 = 531764
421 + 531343 = 531764
433 + 531331 = 531764

Showing the first eight; more decompositions exist.
