Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487472, here are decompositions:

3 + 487469 = 487472
43 + 487429 = 487472
109 + 487363 = 487472
211 + 487261 = 487472
373 + 487099 = 487472
379 + 487093 = 487472
421 + 487051 = 487472
523 + 486949 = 487472

Showing the first eight; more decompositions exist.
