Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493430, here are decompositions:

31 + 493399 = 493430
37 + 493393 = 493430
61 + 493369 = 493430
79 + 493351 = 493430
97 + 493333 = 493430
139 + 493291 = 493430
151 + 493279 = 493430
181 + 493249 = 493430

Showing the first eight; more decompositions exist.
