Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40928, here are decompositions:

31 + 40897 = 40928
61 + 40867 = 40928
79 + 40849 = 40928
109 + 40819 = 40928
127 + 40801 = 40928
157 + 40771 = 40928
229 + 40699 = 40928
331 + 40597 = 40928

Showing the first eight; more decompositions exist.
