Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492178, here are decompositions:

101 + 492077 = 492178
131 + 492047 = 492178
149 + 492029 = 492178
227 + 491951 = 492178
311 + 491867 = 492178
359 + 491819 = 492178
389 + 491789 = 492178
431 + 491747 = 492178

Showing the first eight; more decompositions exist.
