Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481864, here are decompositions:

3 + 481861 = 481864
17 + 481847 = 481864
113 + 481751 = 481864
167 + 481697 = 481864
191 + 481673 = 481864
197 + 481667 = 481864
293 + 481571 = 481864
431 + 481433 = 481864

Showing the first eight; more decompositions exist.
