Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101156, here are decompositions:

7 + 101149 = 101156
37 + 101119 = 101156
43 + 101113 = 101156
67 + 101089 = 101156
157 + 100999 = 101156
199 + 100957 = 101156
229 + 100927 = 101156
409 + 100747 = 101156

Showing the first eight; more decompositions exist.
