Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547818, here are decompositions:

31 + 547787 = 547818
71 + 547747 = 547818
109 + 547709 = 547818
137 + 547681 = 547818
157 + 547661 = 547818
179 + 547639 = 547818
191 + 547627 = 547818
199 + 547619 = 547818

Showing the first eight; more decompositions exist.
