Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71642, here are decompositions:

73 + 71569 = 71642
79 + 71563 = 71642
139 + 71503 = 71642
163 + 71479 = 71642
199 + 71443 = 71642
223 + 71419 = 71642
229 + 71413 = 71642
283 + 71359 = 71642

Showing the first eight; more decompositions exist.
