Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71292, here are decompositions:

5 + 71287 = 71292
29 + 71263 = 71292
31 + 71261 = 71292
43 + 71249 = 71292
59 + 71233 = 71292
83 + 71209 = 71292
101 + 71191 = 71292
131 + 71161 = 71292

Showing the first eight; more decompositions exist.
