Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488144, here are decompositions:

211 + 487933 = 488144
271 + 487873 = 488144
313 + 487831 = 488144
463 + 487681 = 488144
487 + 487657 = 488144
541 + 487603 = 488144
673 + 487471 = 488144
757 + 487387 = 488144

Showing the first eight; more decompositions exist.
