Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71554, here are decompositions:

3 + 71551 = 71554
5 + 71549 = 71554
17 + 71537 = 71554
71 + 71483 = 71554
83 + 71471 = 71554
101 + 71453 = 71554
167 + 71387 = 71554
191 + 71363 = 71554

Showing the first eight; more decompositions exist.
