Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11658, here are decompositions:

37 + 11621 = 11658
41 + 11617 = 11658
61 + 11597 = 11658
71 + 11587 = 11658
79 + 11579 = 11658
107 + 11551 = 11658
109 + 11549 = 11658
131 + 11527 = 11658

Showing the first eight; more decompositions exist.
