Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6490, here are decompositions:

17 + 6473 = 6490
41 + 6449 = 6490
101 + 6389 = 6490
131 + 6359 = 6490
137 + 6353 = 6490
167 + 6323 = 6490
173 + 6317 = 6490
179 + 6311 = 6490

Showing the first eight; more decompositions exist.
