Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71654, here are decompositions:

7 + 71647 = 71654
61 + 71593 = 71654
103 + 71551 = 71654
127 + 71527 = 71654
151 + 71503 = 71654
181 + 71473 = 71654
211 + 71443 = 71654
241 + 71413 = 71654

Showing the first eight; more decompositions exist.
