Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 459820, here are decompositions:

3 + 459817 = 459820
17 + 459803 = 459820
29 + 459791 = 459820
71 + 459749 = 459820
149 + 459671 = 459820
173 + 459647 = 459820
197 + 459623 = 459820
227 + 459593 = 459820

Showing the first eight; more decompositions exist.
