Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150740, here are decompositions:

19 + 150721 = 150740
43 + 150697 = 150740
151 + 150589 = 150740
157 + 150583 = 150740
181 + 150559 = 150740
223 + 150517 = 150740
313 + 150427 = 150740
367 + 150373 = 150740

Showing the first eight; more decompositions exist.
