Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 464890, here are decompositions:

11 + 464879 = 464890
47 + 464843 = 464890
71 + 464819 = 464890
89 + 464801 = 464890
113 + 464777 = 464890
137 + 464753 = 464890
149 + 464741 = 464890
191 + 464699 = 464890

Showing the first eight; more decompositions exist.
