Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101642, here are decompositions:

31 + 101611 = 101642
43 + 101599 = 101642
61 + 101581 = 101642
109 + 101533 = 101642
139 + 101503 = 101642
193 + 101449 = 101642
223 + 101419 = 101642
283 + 101359 = 101642

Showing the first eight; more decompositions exist.
