Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493648, here are decompositions:

5 + 493643 = 493648
41 + 493607 = 493648
107 + 493541 = 493648
167 + 493481 = 493648
191 + 493457 = 493648
251 + 493397 = 493648
347 + 493301 = 493648
431 + 493217 = 493648

Showing the first eight; more decompositions exist.
