Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87090, here are decompositions:

7 + 87083 = 87090
19 + 87071 = 87090
41 + 87049 = 87090
53 + 87037 = 87090
79 + 87011 = 87090
97 + 86993 = 87090
109 + 86981 = 87090
131 + 86959 = 87090

Showing the first eight; more decompositions exist.
