Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492148, here are decompositions:

71 + 492077 = 492148
89 + 492059 = 492148
101 + 492047 = 492148
131 + 492017 = 492148
179 + 491969 = 492148
197 + 491951 = 492148
281 + 491867 = 492148
311 + 491837 = 492148

Showing the first eight; more decompositions exist.
