Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86906, here are decompositions:

37 + 86869 = 86906
139 + 86767 = 86906
163 + 86743 = 86906
229 + 86677 = 86906
277 + 86629 = 86906
307 + 86599 = 86906
367 + 86539 = 86906
373 + 86533 = 86906

Showing the first eight; more decompositions exist.
