Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487448, here are decompositions:

19 + 487429 = 487448
61 + 487387 = 487448
67 + 487381 = 487448
229 + 487219 = 487448
271 + 487177 = 487448
337 + 487111 = 487448
349 + 487099 = 487448
397 + 487051 = 487448

Showing the first eight; more decompositions exist.
