Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531814, here are decompositions:

83 + 531731 = 531814
113 + 531701 = 531814
191 + 531623 = 531814
233 + 531581 = 531814
263 + 531551 = 531814
293 + 531521 = 531814
317 + 531497 = 531814
431 + 531383 = 531814

Showing the first eight; more decompositions exist.
