Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86740, here are decompositions:

11 + 86729 = 86740
29 + 86711 = 86740
47 + 86693 = 86740
113 + 86627 = 86740
167 + 86573 = 86740
179 + 86561 = 86740
239 + 86501 = 86740
263 + 86477 = 86740

Showing the first eight; more decompositions exist.
