Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71388, here are decompositions:

29 + 71359 = 71388
41 + 71347 = 71388
47 + 71341 = 71388
59 + 71329 = 71388
61 + 71327 = 71388
71 + 71317 = 71388
101 + 71287 = 71388
127 + 71261 = 71388

Showing the first eight; more decompositions exist.
