Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485828, here are decompositions:

97 + 485731 = 485828
127 + 485701 = 485828
139 + 485689 = 485828
157 + 485671 = 485828
181 + 485647 = 485828
241 + 485587 = 485828
331 + 485497 = 485828
349 + 485479 = 485828

Showing the first eight; more decompositions exist.
