Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526142, here are decompositions:

3 + 526139 = 526142
73 + 526069 = 526142
79 + 526063 = 526142
163 + 525979 = 526142
181 + 525961 = 526142
193 + 525949 = 526142
229 + 525913 = 526142
271 + 525871 = 526142

Showing the first eight; more decompositions exist.
