Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494242, here are decompositions:

5 + 494237 = 494242
29 + 494213 = 494242
101 + 494141 = 494242
113 + 494129 = 494242
149 + 494093 = 494242
173 + 494069 = 494242
191 + 494051 = 494242
263 + 493979 = 494242

Showing the first eight; more decompositions exist.
