Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471818, here are decompositions:

37 + 471781 = 471818
97 + 471721 = 471818
199 + 471619 = 471818
211 + 471607 = 471818
229 + 471589 = 471818
331 + 471487 = 471818
337 + 471481 = 471818
367 + 471451 = 471818

Showing the first eight; more decompositions exist.
