Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488090, here are decompositions:

79 + 488011 = 488090
157 + 487933 = 488090
193 + 487897 = 488090
199 + 487891 = 488090
271 + 487819 = 488090
307 + 487783 = 488090
349 + 487741 = 488090
373 + 487717 = 488090

Showing the first eight; more decompositions exist.
