Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472864, here are decompositions:

5 + 472859 = 472864
17 + 472847 = 472864
47 + 472817 = 472864
71 + 472793 = 472864
101 + 472763 = 472864
113 + 472751 = 472864
167 + 472697 = 472864
173 + 472691 = 472864

Showing the first eight; more decompositions exist.
