Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85826, here are decompositions:

7 + 85819 = 85826
109 + 85717 = 85826
157 + 85669 = 85826
199 + 85627 = 85826
229 + 85597 = 85826
277 + 85549 = 85826
313 + 85513 = 85826
373 + 85453 = 85826

Showing the first eight; more decompositions exist.
