Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493742, here are decompositions:

13 + 493729 = 493742
31 + 493711 = 493742
163 + 493579 = 493742
211 + 493531 = 493742
349 + 493393 = 493742
373 + 493369 = 493742
409 + 493333 = 493742
463 + 493279 = 493742

Showing the first eight; more decompositions exist.
