Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83906, here are decompositions:

3 + 83903 = 83906
37 + 83869 = 83906
73 + 83833 = 83906
349 + 83557 = 83906
409 + 83497 = 83906
457 + 83449 = 83906
463 + 83443 = 83906
499 + 83407 = 83906

Showing the first eight; more decompositions exist.
