Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71546, here are decompositions:

19 + 71527 = 71546
43 + 71503 = 71546
67 + 71479 = 71546
73 + 71473 = 71546
103 + 71443 = 71546
109 + 71437 = 71546
127 + 71419 = 71546
157 + 71389 = 71546

Showing the first eight; more decompositions exist.
