Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3250, here are decompositions:

29 + 3221 = 3250
41 + 3209 = 3250
47 + 3203 = 3250
59 + 3191 = 3250
83 + 3167 = 3250
113 + 3137 = 3250
131 + 3119 = 3250
167 + 3083 = 3250

Showing the first eight; more decompositions exist.
