Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101646, here are decompositions:

5 + 101641 = 101646
19 + 101627 = 101646
43 + 101603 = 101646
47 + 101599 = 101646
73 + 101573 = 101646
109 + 101537 = 101646
113 + 101533 = 101646
157 + 101489 = 101646

Showing the first eight; more decompositions exist.
