Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75740, here are decompositions:

19 + 75721 = 75740
31 + 75709 = 75740
37 + 75703 = 75740
61 + 75679 = 75740
157 + 75583 = 75740
163 + 75577 = 75740
199 + 75541 = 75740
229 + 75511 = 75740

Showing the first eight; more decompositions exist.
