Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488478, here are decompositions:

5 + 488473 = 488478
19 + 488459 = 488478
37 + 488441 = 488478
59 + 488419 = 488478
61 + 488417 = 488478
71 + 488407 = 488478
79 + 488399 = 488478
97 + 488381 = 488478

Showing the first eight; more decompositions exist.
