Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002290, here are decompositions:

31 + 1002259 = 1002290
43 + 1002247 = 1002290
139 + 1002151 = 1002290
181 + 1002109 = 1002290
199 + 1002091 = 1002290
229 + 1002061 = 1002290
241 + 1002049 = 1002290
307 + 1001983 = 1002290

Showing the first eight; more decompositions exist.
