Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143012, here are decompositions:

19 + 142993 = 143012
31 + 142981 = 143012
43 + 142969 = 143012
73 + 142939 = 143012
109 + 142903 = 143012
139 + 142873 = 143012
223 + 142789 = 143012
241 + 142771 = 143012

Showing the first eight; more decompositions exist.
