Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71612, here are decompositions:

19 + 71593 = 71612
43 + 71569 = 71612
61 + 71551 = 71612
109 + 71503 = 71612
139 + 71473 = 71612
193 + 71419 = 71612
199 + 71413 = 71612
223 + 71389 = 71612

Showing the first eight; more decompositions exist.
