Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494198, here are decompositions:

7 + 494191 = 494198
31 + 494167 = 494198
97 + 494101 = 494198
157 + 494041 = 494198
421 + 493777 = 494198
487 + 493711 = 494198
541 + 493657 = 494198
571 + 493627 = 494198

Showing the first eight; more decompositions exist.
