Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488442, here are decompositions:

23 + 488419 = 488442
41 + 488401 = 488442
43 + 488399 = 488442
61 + 488381 = 488442
89 + 488353 = 488442
103 + 488339 = 488442
109 + 488333 = 488442
113 + 488329 = 488442

Showing the first eight; more decompositions exist.
