Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85784, here are decompositions:

3 + 85781 = 85784
67 + 85717 = 85784
73 + 85711 = 85784
157 + 85627 = 85784
163 + 85621 = 85784
271 + 85513 = 85784
331 + 85453 = 85784
337 + 85447 = 85784

Showing the first eight; more decompositions exist.
