Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943538, here are decompositions:

61 + 943477 = 943538
67 + 943471 = 943538
109 + 943429 = 943538
151 + 943387 = 943538
181 + 943357 = 943538
307 + 943231 = 943538
457 + 943081 = 943538
691 + 942847 = 943538

Showing the first eight; more decompositions exist.
