Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89130, here are decompositions:

7 + 89123 = 89130
11 + 89119 = 89130
17 + 89113 = 89130
23 + 89107 = 89130
29 + 89101 = 89130
43 + 89087 = 89130
47 + 89083 = 89130
59 + 89071 = 89130

Showing the first eight; more decompositions exist.
