Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494042, here are decompositions:

13 + 494029 = 494042
19 + 494023 = 494042
103 + 493939 = 494042
229 + 493813 = 494042
313 + 493729 = 494042
331 + 493711 = 494042
349 + 493693 = 494042
421 + 493621 = 494042

Showing the first eight; more decompositions exist.
