Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488722, here are decompositions:

5 + 488717 = 488722
11 + 488711 = 488722
71 + 488651 = 488722
83 + 488639 = 488722
89 + 488633 = 488722
149 + 488573 = 488722
263 + 488459 = 488722
281 + 488441 = 488722

Showing the first eight; more decompositions exist.
