Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101678, here are decompositions:

37 + 101641 = 101678
67 + 101611 = 101678
79 + 101599 = 101678
97 + 101581 = 101678
151 + 101527 = 101678
211 + 101467 = 101678
229 + 101449 = 101678
331 + 101347 = 101678

Showing the first eight; more decompositions exist.
