Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87930, here are decompositions:

13 + 87917 = 87930
19 + 87911 = 87930
43 + 87887 = 87930
53 + 87877 = 87930
61 + 87869 = 87930
97 + 87833 = 87930
127 + 87803 = 87930
137 + 87793 = 87930

Showing the first eight; more decompositions exist.
