Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492742, here are decompositions:

11 + 492731 = 492742
23 + 492719 = 492742
71 + 492671 = 492742
83 + 492659 = 492742
101 + 492641 = 492742
113 + 492629 = 492742
179 + 492563 = 492742
191 + 492551 = 492742

Showing the first eight; more decompositions exist.
