Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71906, here are decompositions:

7 + 71899 = 71906
19 + 71887 = 71906
97 + 71809 = 71906
193 + 71713 = 71906
199 + 71707 = 71906
313 + 71593 = 71906
337 + 71569 = 71906
379 + 71527 = 71906

Showing the first eight; more decompositions exist.
