Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547942, here are decompositions:

41 + 547901 = 547942
53 + 547889 = 547942
71 + 547871 = 547942
89 + 547853 = 547942
173 + 547769 = 547942
179 + 547763 = 547942
233 + 547709 = 547942
281 + 547661 = 547942

Showing the first eight; more decompositions exist.
