Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761138, here are decompositions:

5 + 8761133 = 8761138
59 + 8761079 = 8761138
101 + 8761037 = 8761138
131 + 8761007 = 8761138
179 + 8760959 = 8761138
227 + 8760911 = 8761138
359 + 8760779 = 8761138
467 + 8760671 = 8761138

Showing the first eight; more decompositions exist.
