Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486644, here are decompositions:

3 + 486641 = 486644
7 + 486637 = 486644
43 + 486601 = 486644
61 + 486583 = 486644
163 + 486481 = 486644
211 + 486433 = 486644
313 + 486331 = 486644
331 + 486313 = 486644

Showing the first eight; more decompositions exist.
