Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4490, here are decompositions:

7 + 4483 = 4490
43 + 4447 = 4490
67 + 4423 = 4490
127 + 4363 = 4490
151 + 4339 = 4490
163 + 4327 = 4490
193 + 4297 = 4490
229 + 4261 = 4490

Showing the first eight; more decompositions exist.
