Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493478, here are decompositions:

31 + 493447 = 493478
79 + 493399 = 493478
109 + 493369 = 493478
127 + 493351 = 493478
199 + 493279 = 493478
229 + 493249 = 493478
277 + 493201 = 493478
331 + 493147 = 493478

Showing the first eight; more decompositions exist.
