Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151086, here are decompositions:

29 + 151057 = 151086
37 + 151049 = 151086
59 + 151027 = 151086
73 + 151013 = 151086
79 + 151007 = 151086
97 + 150989 = 151086
107 + 150979 = 151086
127 + 150959 = 151086

Showing the first eight; more decompositions exist.
