Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71786, here are decompositions:

67 + 71719 = 71786
73 + 71713 = 71786
79 + 71707 = 71786
139 + 71647 = 71786
193 + 71593 = 71786
223 + 71563 = 71786
283 + 71503 = 71786
307 + 71479 = 71786

Showing the first eight; more decompositions exist.
