Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538154, here are decompositions:

3 + 538151 = 538154
7 + 538147 = 538154
31 + 538123 = 538154
37 + 538117 = 538154
61 + 538093 = 538154
103 + 538051 = 538154
163 + 537991 = 538154
241 + 537913 = 538154

Showing the first eight; more decompositions exist.
