Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7928, here are decompositions:

61 + 7867 = 7928
139 + 7789 = 7928
211 + 7717 = 7928
229 + 7699 = 7928
241 + 7687 = 7928
307 + 7621 = 7928
337 + 7591 = 7928
367 + 7561 = 7928

Showing the first eight; more decompositions exist.
