Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153500, here are decompositions:

13 + 153487 = 153500
31 + 153469 = 153500
43 + 153457 = 153500
73 + 153427 = 153500
79 + 153421 = 153500
157 + 153343 = 153500
163 + 153337 = 153500
181 + 153319 = 153500

Showing the first eight; more decompositions exist.
