Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547840, here are decompositions:

17 + 547823 = 547840
23 + 547817 = 547840
53 + 547787 = 547840
71 + 547769 = 547840
113 + 547727 = 547840
131 + 547709 = 547840
179 + 547661 = 547840
197 + 547643 = 547840

Showing the first eight; more decompositions exist.
