Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101138, here are decompositions:

19 + 101119 = 101138
31 + 101107 = 101138
139 + 100999 = 101138
151 + 100987 = 101138
157 + 100981 = 101138
181 + 100957 = 101138
211 + 100927 = 101138
337 + 100801 = 101138

Showing the first eight; more decompositions exist.
