Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145086, here are decompositions:

17 + 145069 = 145086
23 + 145063 = 145086
43 + 145043 = 145086
79 + 145007 = 145086
103 + 144983 = 145086
113 + 144973 = 145086
197 + 144889 = 145086
199 + 144887 = 145086

Showing the first eight; more decompositions exist.
