Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472830, here are decompositions:

13 + 472817 = 472830
31 + 472799 = 472830
37 + 472793 = 472830
67 + 472763 = 472830
79 + 472751 = 472830
89 + 472741 = 472830
109 + 472721 = 472830
139 + 472691 = 472830

Showing the first eight; more decompositions exist.
