Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85628, here are decompositions:

7 + 85621 = 85628
31 + 85597 = 85628
79 + 85549 = 85628
97 + 85531 = 85628
181 + 85447 = 85628
199 + 85429 = 85628
331 + 85297 = 85628
541 + 85087 = 85628

Showing the first eight; more decompositions exist.
