Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488890, here are decompositions:

11 + 488879 = 488890
29 + 488861 = 488890
131 + 488759 = 488890
167 + 488723 = 488890
173 + 488717 = 488890
179 + 488711 = 488890
239 + 488651 = 488890
251 + 488639 = 488890

Showing the first eight; more decompositions exist.
