Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142974, here are decompositions:

5 + 142969 = 142974
11 + 142963 = 142974
67 + 142907 = 142974
71 + 142903 = 142974
101 + 142873 = 142974
103 + 142871 = 142974
107 + 142867 = 142974
137 + 142837 = 142974

Showing the first eight; more decompositions exist.
