Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85844, here are decompositions:

7 + 85837 = 85844
13 + 85831 = 85844
127 + 85717 = 85844
223 + 85621 = 85844
313 + 85531 = 85844
331 + 85513 = 85844
397 + 85447 = 85844
433 + 85411 = 85844

Showing the first eight; more decompositions exist.
