Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540942, here are decompositions:

41 + 540901 = 540942
71 + 540871 = 540942
79 + 540863 = 540942
139 + 540803 = 540942
163 + 540779 = 540942
173 + 540769 = 540942
191 + 540751 = 540942
229 + 540713 = 540942

Showing the first eight; more decompositions exist.
