Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488228, here are decompositions:

19 + 488209 = 488228
31 + 488197 = 488228
67 + 488161 = 488228
79 + 488149 = 488228
109 + 488119 = 488228
331 + 487897 = 488228
337 + 487891 = 488228
397 + 487831 = 488228

Showing the first eight; more decompositions exist.
