Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71432, here are decompositions:

3 + 71429 = 71432
13 + 71419 = 71432
19 + 71413 = 71432
43 + 71389 = 71432
73 + 71359 = 71432
79 + 71353 = 71432
103 + 71329 = 71432
139 + 71293 = 71432

Showing the first eight; more decompositions exist.
