Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006690, here are decompositions:

53 + 1006637 = 1006690
101 + 1006589 = 1006690
107 + 1006583 = 1006690
131 + 1006559 = 1006690
197 + 1006493 = 1006690
227 + 1006463 = 1006690
257 + 1006433 = 1006690
353 + 1006337 = 1006690

Showing the first eight; more decompositions exist.
