Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492442, here are decompositions:

11 + 492431 = 492442
29 + 492413 = 492442
53 + 492389 = 492442
149 + 492293 = 492442
191 + 492251 = 492442
359 + 492083 = 492442
383 + 492059 = 492442
389 + 492053 = 492442

Showing the first eight; more decompositions exist.
