Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101540, here are decompositions:

3 + 101537 = 101540
7 + 101533 = 101540
13 + 101527 = 101540
37 + 101503 = 101540
73 + 101467 = 101540
157 + 101383 = 101540
163 + 101377 = 101540
181 + 101359 = 101540

Showing the first eight; more decompositions exist.
