Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188126, here are decompositions:

19 + 188107 = 188126
97 + 188029 = 188126
109 + 188017 = 188126
139 + 187987 = 188126
163 + 187963 = 188126
199 + 187927 = 188126
229 + 187897 = 188126
283 + 187843 = 188126

Showing the first eight; more decompositions exist.
