Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188010, here are decompositions:

23 + 187987 = 188010
37 + 187973 = 188010
47 + 187963 = 188010
59 + 187951 = 188010
79 + 187931 = 188010
83 + 187927 = 188010
89 + 187921 = 188010
101 + 187909 = 188010

Showing the first eight; more decompositions exist.
