Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492138, here are decompositions:

61 + 492077 = 492138
71 + 492067 = 492138
79 + 492059 = 492138
109 + 492029 = 492138
131 + 492007 = 492138
239 + 491899 = 492138
271 + 491867 = 492138
281 + 491857 = 492138

Showing the first eight; more decompositions exist.
