Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143040, here are decompositions:

47 + 142993 = 143040
59 + 142981 = 143040
61 + 142979 = 143040
67 + 142973 = 143040
71 + 142969 = 143040
101 + 142939 = 143040
137 + 142903 = 143040
167 + 142873 = 143040

Showing the first eight; more decompositions exist.
