Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101772, here are decompositions:

23 + 101749 = 101772
31 + 101741 = 101772
53 + 101719 = 101772
71 + 101701 = 101772
79 + 101693 = 101772
109 + 101663 = 101772
131 + 101641 = 101772
173 + 101599 = 101772

Showing the first eight; more decompositions exist.
