Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488542, here are decompositions:

3 + 488539 = 488542
29 + 488513 = 488542
83 + 488459 = 488542
101 + 488441 = 488542
233 + 488309 = 488542
239 + 488303 = 488542
281 + 488261 = 488542
293 + 488249 = 488542

Showing the first eight; more decompositions exist.
