Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471830, here are decompositions:

13 + 471817 = 471830
61 + 471769 = 471830
109 + 471721 = 471830
127 + 471703 = 471830
157 + 471673 = 471830
181 + 471649 = 471830
211 + 471619 = 471830
223 + 471607 = 471830

Showing the first eight; more decompositions exist.
