Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71648, here are decompositions:

79 + 71569 = 71648
97 + 71551 = 71648
211 + 71437 = 71648
229 + 71419 = 71648
307 + 71341 = 71648
331 + 71317 = 71648
439 + 71209 = 71648
457 + 71191 = 71648

Showing the first eight; more decompositions exist.
