Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497142, here are decompositions:

5 + 497137 = 497142
29 + 497113 = 497142
31 + 497111 = 497142
73 + 497069 = 497142
101 + 497041 = 497142
131 + 497011 = 497142
179 + 496963 = 497142
193 + 496949 = 497142

Showing the first eight; more decompositions exist.
