Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005590, here are decompositions:

37 + 1005553 = 1005590
97 + 1005493 = 1005590
109 + 1005481 = 1005590
151 + 1005439 = 1005590
163 + 1005427 = 1005590
181 + 1005409 = 1005590
199 + 1005391 = 1005590
241 + 1005349 = 1005590

Showing the first eight; more decompositions exist.
