Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140870, here are decompositions:

3 + 140867 = 140870
7 + 140863 = 140870
31 + 140839 = 140870
43 + 140827 = 140870
73 + 140797 = 140870
97 + 140773 = 140870
109 + 140761 = 140870
139 + 140731 = 140870

Showing the first eight; more decompositions exist.
