Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488872, here are decompositions:

11 + 488861 = 488872
113 + 488759 = 488872
149 + 488723 = 488872
233 + 488639 = 488872
239 + 488633 = 488872
269 + 488603 = 488872
359 + 488513 = 488872
431 + 488441 = 488872

Showing the first eight; more decompositions exist.
