Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71966, here are decompositions:

3 + 71963 = 71966
19 + 71947 = 71966
67 + 71899 = 71966
79 + 71887 = 71966
157 + 71809 = 71966
373 + 71593 = 71966
397 + 71569 = 71966
439 + 71527 = 71966

Showing the first eight; more decompositions exist.
