Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487874, here are decompositions:

31 + 487843 = 487874
43 + 487831 = 487874
157 + 487717 = 487874
193 + 487681 = 487874
223 + 487651 = 487874
271 + 487603 = 487874
313 + 487561 = 487874
367 + 487507 = 487874

Showing the first eight; more decompositions exist.
