Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71430, here are decompositions:

11 + 71419 = 71430
17 + 71413 = 71430
19 + 71411 = 71430
31 + 71399 = 71430
41 + 71389 = 71430
43 + 71387 = 71430
67 + 71363 = 71430
71 + 71359 = 71430

Showing the first eight; more decompositions exist.
