Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481290, here are decompositions:

41 + 481249 = 481290
59 + 481231 = 481290
79 + 481211 = 481290
83 + 481207 = 481290
109 + 481181 = 481290
113 + 481177 = 481290
137 + 481153 = 481290
149 + 481141 = 481290

Showing the first eight; more decompositions exist.
