Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493520, here are decompositions:

73 + 493447 = 493520
127 + 493393 = 493520
151 + 493369 = 493520
229 + 493291 = 493520
241 + 493279 = 493520
271 + 493249 = 493520
277 + 493243 = 493520
373 + 493147 = 493520

Showing the first eight; more decompositions exist.
