Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186562, here are decompositions:

11 + 186551 = 186562
83 + 186479 = 186562
251 + 186311 = 186562
263 + 186299 = 186562
401 + 186161 = 186562
443 + 186119 = 186562
449 + 186113 = 186562
491 + 186071 = 186562

Showing the first eight; more decompositions exist.
