Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540938, here are decompositions:

31 + 540907 = 540938
37 + 540901 = 540938
61 + 540877 = 540938
67 + 540871 = 540938
157 + 540781 = 540938
241 + 540697 = 540938
379 + 540559 = 540938
397 + 540541 = 540938

Showing the first eight; more decompositions exist.
