Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494156, here are decompositions:

73 + 494083 = 494156
79 + 494077 = 494156
127 + 494029 = 494156
163 + 493993 = 494156
283 + 493873 = 494156
349 + 493807 = 494156
379 + 493777 = 494156
409 + 493747 = 494156

Showing the first eight; more decompositions exist.
