Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153740, here are decompositions:

7 + 153733 = 153740
151 + 153589 = 153740
211 + 153529 = 153740
229 + 153511 = 153740
241 + 153499 = 153740
271 + 153469 = 153740
283 + 153457 = 153740
313 + 153427 = 153740

Showing the first eight; more decompositions exist.
