Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27690, here are decompositions:

17 + 27673 = 27690
37 + 27653 = 27690
43 + 27647 = 27690
59 + 27631 = 27690
73 + 27617 = 27690
79 + 27611 = 27690
107 + 27583 = 27690
109 + 27581 = 27690

Showing the first eight; more decompositions exist.
