Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 292, here are decompositions:

11 + 281 = 292
23 + 269 = 292
29 + 263 = 292
41 + 251 = 292
53 + 239 = 292
59 + 233 = 292
101 + 191 = 292
113 + 179 = 292

Showing the first eight; more decompositions exist.
