Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3500, here are decompositions:

31 + 3469 = 3500
37 + 3463 = 3500
43 + 3457 = 3500
67 + 3433 = 3500
109 + 3391 = 3500
127 + 3373 = 3500
139 + 3361 = 3500
157 + 3343 = 3500

Showing the first eight; more decompositions exist.
