Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173140, here are decompositions:

3 + 173137 = 173140
41 + 173099 = 173140
53 + 173087 = 173140
59 + 173081 = 173140
101 + 173039 = 173140
167 + 172973 = 173140
257 + 172883 = 173140
263 + 172877 = 173140

Showing the first eight; more decompositions exist.
