Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152740, here are decompositions:

11 + 152729 = 152740
17 + 152723 = 152740
23 + 152717 = 152740
59 + 152681 = 152740
83 + 152657 = 152740
101 + 152639 = 152740
173 + 152567 = 152740
239 + 152501 = 152740

Showing the first eight; more decompositions exist.
