Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87230, here are decompositions:

7 + 87223 = 87230
19 + 87211 = 87230
43 + 87187 = 87230
79 + 87151 = 87230
97 + 87133 = 87230
109 + 87121 = 87230
127 + 87103 = 87230
181 + 87049 = 87230

Showing the first eight; more decompositions exist.
