Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143090, here are decompositions:

37 + 143053 = 143090
97 + 142993 = 143090
109 + 142981 = 143090
127 + 142963 = 143090
151 + 142939 = 143090
193 + 142897 = 143090
223 + 142867 = 143090
331 + 142759 = 143090

Showing the first eight; more decompositions exist.
