Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493664, here are decompositions:

7 + 493657 = 493664
37 + 493627 = 493664
43 + 493621 = 493664
97 + 493567 = 493664
271 + 493393 = 493664
313 + 493351 = 493664
331 + 493333 = 493664
373 + 493291 = 493664

Showing the first eight; more decompositions exist.
