Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140900, here are decompositions:

3 + 140897 = 140900
7 + 140893 = 140900
31 + 140869 = 140900
37 + 140863 = 140900
61 + 140839 = 140900
73 + 140827 = 140900
103 + 140797 = 140900
127 + 140773 = 140900

Showing the first eight; more decompositions exist.
