Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494078, here are decompositions:

37 + 494041 = 494078
139 + 493939 = 494078
181 + 493897 = 494078
271 + 493807 = 494078
331 + 493747 = 494078
349 + 493729 = 494078
367 + 493711 = 494078
421 + 493657 = 494078

Showing the first eight; more decompositions exist.
