Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71630, here are decompositions:

37 + 71593 = 71630
61 + 71569 = 71630
67 + 71563 = 71630
79 + 71551 = 71630
103 + 71527 = 71630
127 + 71503 = 71630
151 + 71479 = 71630
157 + 71473 = 71630

Showing the first eight; more decompositions exist.
